69 Z/28 with Max-G Chassis
 
Hello All,

My car is a true 1969 Camaro Z/28. Since i didnt have the original engine, tranny, or rear end and since I bought it i decided to go the pro-touring route instead of original. This is round two of my project. Round one involves a sappy story about some "professional" I took my car to for some sheetmetal removal/replacement. This is how it looked before I picked it up from the "professional shop."

http://i1012.photobucket.com/albums/...o/P6180028.jpg


I decided to attempt to put the car back together myself and at that time the plan was to put an Art Morrison back half and seperate AME front subframe in place then weld in the connectors. After a brief hiatus of doing nothing to the car and primarily visiting this site to read the Investing 102 thread, I have since sold the backhalf and got a full Art Morrison Max-G chassis from a shop down the road from me called Pyramid Street Rods. These guys are dealers for Art Morrison and some of the most honest people you will ever meet. So i put the frame on a jig, got it all leveled and centered, BRACED the car and cut the floor out. I also realized i screwed up the wheel wells so those will be going bye bye pretty soon here.

Here are some pics of the progress so far:

I think using this jig and having everything level is going to work out a LOT better than my first attempt where i had everything on jackstands with a shim here, a shim there, a shim everywhere...

And some pics of the bracing and floor removal...

Since my plan is to work on the car myself and my time doesnt cost any money, i would like to try and make the frame removable from the body instead of welding the two together when i make my floor panels. I am not quite sure the best way of doing this yet, but i have studied some photo's of the the shop RK Collections that did accomplish this. Here's there site if youre interested... http://www.rkmotorscharlotte.com/pc/...-Camaro/132163

P.S. I realize I have bit off more than i can chew and took on a project that requires way more experience than i have, but nothing like learning by diving in head first right!! That and having a whole lot of this :cheers:

Thanks in advance to all who help contribute to this build. Hopefully Round 2 turns out better than Round 1:lateral:

just keep measuring all the time, and make sure your reference points are square and unchanging. Every shim, twist, and move you make will affect something else so always be thinking 3 dimensionally, and every 30 minutes stand back as far as you can and take a look at the "squareness", and don't forget to choose new "angles" to look at the car from not just the same place every time. Have several long straight edges and definitely buy a digital level, I use that thing all the time.

I've dropped my body in various states on top of 2 or 3 chassis now and I'm just a dude with a carport. My first time I had the body with no floor and no real bracing stood up on 6-8 cinder blocks while I rolled the completed chassis, roll cage and all, underneath it on furniture dollies. The last one I started with just a roof and a-pillars, so less structure and form than you have. Again I'm just a one man amateur show out in a carport. Give that garage space you have you are a luxurious shop. You can do it !

Looking good. I'm assuming you know that the roof panel got whacked about 2" above where it meets the quarters, right? That line of drilled out spot welds on the inner structure below the roof cut is where the quarter attachs, and the roof slips down over it. You may end up putting a new roof skin on if you don't want to have to fab up a 2" wide patch to tie the roof and quarter together- that area has a lot of curve/shape to it and isn't something I'd want to try to make look right with a patch.

67pro-street 12-12-2012 03:25 PM

Thanks for the comments everyone. I hope to get some more work done between now and the new year. I will post pics as i make progress!

BobK yes i realize the roofline is cut too high. I still have the two original pieces though. I was going to try and put a thin strip of 18 gauge metal behind the roofline and plug weld it into place using half the strip. then put the original piece up there and plug weld that to the other half of the strip, leaving ~1/32" gap between the two pieces. Then i will spot weld the two roof pieces together. My hope here is that i wont warp the roof material when it cools after welding and will want to shrink in. I am also hoping to avoid ghost lines in the paint by spot welding the two together since that part will be at eye level. If that doesnt work, then i can look into roof replacement. The pics dont show it, but it is rotted out along the rear window channel so i need to address that as well. Clear as mud?!


canrc, thanks for the offer i may take you up on that in the new year when all the holiday rush across the border dies down. I checked out your build, Rybar posted it and that is a sweet camaro! Rybar's is pretty nice too! My original colors were garnet red with black stripes which is what i was thinking of going back with on my car. But i dont know if the car gods will allow two pro-touring cars within 100 miles of each other to have the same paint scheme!!

67pro-street 11-05-2013 03:52 PM

Been about a year and haven't had a chance to touch the car much until recently. One of my goals was to keep the body removable from the frame. I had a hard time trying to figure out how i was going to do that so basically I was too scared to touch the car until I did. I have to give a lot of credit to Gary Betsy on my final solution. He build the Voracious Cuda on this site. Anways, once i had my game plan, it was pretty easy to execute the plan...like two weekends!

Basically i took the art morrison frame and started created a sub structure on top of the frame using 3/16" flat bar. I will then take that sub structure and weld it to the body of the car. That substructure will then bolt up to the AME frame and have polyurethane pads in between.

You can see the pilot holes drilled into the frame. Eventually the threaded bungs will be welded in these spots. It was next to impossible to bring myself to drilling/welding to this frame...once i did though i was happy with the results.

67pro-street 11-05-2013 03:58 PM

Here is the substructure i built. It will eventually be welded to the body of the car.

http://i1012.photobucket.com/albums/...psijxlwskg.jpg

And here it is after all bungs welded, grinded smooth, and then bolted into place with the polyurethane pads. I used 1/4" pads, think that is enough space between the AME frame and the substructure? I am thinking i will be okay since i used 3/16" flatbar for the substructure and then the floor pans will be welded to that. shouldnt flex too much, but im open to suggestions if others think i should go with 1/2" polyurethane pad.

http://i1012.photobucket.com/albums/...psacefd1d1.jpg

Oh, the flatbar spanning the width was just there for mockup so i dont tweak the substructure. It will eventually go away.

67pro-street 11-05-2013 04:14 PM

Next step was to cut away the inner rockers to allow for the body to slip over the substructure. Following are some pictures, and thats about where the car currently stands. May not look like a lot of work, but its the most I've done in a few years so i am pretty happy! It takes a lot longer to fabricate this stuff when all you are using is an angle grinder and multiple cutting/grinding discs, but its the end results that make this an enjoyable hobby.

Cutline along bottom of outer rocker panel

http://i1012.photobucket.com/albums/...ps46a0de81.jpg

You can see the inner rocker cut away.
http://i1012.photobucket.com/albums/...ps0e26dd6a.jpg

body set on frame. I made it so the substructure and the top of the inner rocker panel will sit flush. Ill bridge the gap with some steel and then start on the rest of the inside/outside sheetmetal. Might be a while till i make some more progress, but moving forward slowly is better than not moving forward at all!! (PS, ill buy a new camera as well, I do realize how much the picture quality sucks!)

Here is what the substructure looks like on the bottom of the rocker. The outer rocker is in pretty rough shape so i plan to modify it and extend down to the bottom of the substructure, thus covering up the AME frame.

thats some good fab work,glad to see you are back to work on it,good luck with it:thumbsup:

preston 11-06-2013 01:01 PM

Happy to see you making progress.

I'm confused though, I thought these bodies were already bolted on to the chassis and that the AM chassis included OEM style body mounts, although of course I don't see them on your chassis.

67pro-street 11-06-2013 01:09 PM

Hey thanks guys, its not a lot of progress but at least its moving forward. Preston, the camaros were unibody construction. AME makes a front clip that bolts on and then you can buy a rear clip that welds to the stock floor. If you go with the Max-G chassis though, the entire floor pan needs to be removed and then replaced with custom floor boards. Hopefully ill have some time this weekend to make some more progress. Ill post updates if i do!

waynieZ 11-06-2013 05:32 PM

67pro-street 11-26-2014 03:17 PM

A year later, and I'm still chipping away at the project. I ripped off the old sheet metal that I initially installed because I didnt know what I was doing and well...I did it wrong. Went with AMD sheet metal the second time around and I was extremely impressed with the quality of the panels. I highly recommend them to anyone looking to purchase new sheet metal.

Here are some photos of me widening the tubs:

67pro-street 11-26-2014 03:24 PM

As stated earlier, I am building the car so that the body is removable from the frame, because of that, i kept about 1/4" to 5/16" gap between the wheel tubs and the frame so that i can remove the body without damaging the paint. Here is how it turned out...

http://i1012.photobucket.com/albums/...ps38c9c639.jpg

http://i1012.photobucket.com/albums/...psc7364060.jpg

I then replaced the package tray as mine was all bent up from the previous shop that had done work on the car. I probably could have straightened it out, but I honestly think it was easier, quicker and cheaper to buy a new panel and replace it.

Last piece of the puzzle was fitting the tail panel. This was tough because there are no trim pieces or anything to cover up the seams where the tailpanel and quarters line up. I had to do a lot of cutting and bending and welding and so on. I was too engrossed to take photos during the process, but finally after years and years of anticipation, I completed that part and got the car of the jig. It is finally sitting on all 4 wheels. I have a few weeks off in December and I hope to finish the floors and the firewall so that i will have a complete roller.

Ruin? I'd say resurrect. The metal was bad, no engine, etc.

Alot of work, great progress. I'd recommend wider tires in the rear though LOL

What was left of that original Z28 to "ruin"? Outstanding work given the learning curve. I completely understand the amount of time & effort when using an angle grinder as your high end fab tool. Go man Go!

Crushing what was left would have defined ruining this car. All new metal is a restoration. Maintains original VIN, and firewall plate.
Great job on this car!

67pro-street 11-27-2014 04:57 PM

Thanks for all the positive comments guys, it really feels good to have the car on the ground. The light at the end of the tunnel is still very far away and very dim, but it's there! This sheet metal stuff is something you can only get good at by doing...The second time around fitting the quarters and wheel tubs and all that went way smoother than the first time. The way the car was left off by the previous shop i took it to left me with little to no reference points of the original body so I was "guessing" a lot about how to put it all back together.

Jay Hilliard 11-27-2014 07:05 PM

You are doing an excellent job and making great progress. Keep plugging away.

GregWeld 11-27-2014 08:42 PM

Nice job! That's a lot of work.. And you did yourself real proud.

hersheys69z 11-27-2014 09:53 PM

Ya it probably is better then the body I'm starting with. My car took a pole in the drivers door, roof and rocker.
Not worried because that is what I do for a living.
My current project at work is a 1931 Invicta coupe I'm restoring for Pebble Beach Concourse De Elegance next year.
I'm use to re working original junk.
This Invicta was the only coupe ever built and the front fenders are unique to this car hand built out of aluminum in sections and welded together. Being over 80 years old they were absolute garbage from previous owners not having cracks properly repaired and just riveting patches of aluminum over it and covering it up with bondo. Took me a couple months to repair and now they are concours quality inside and out. Sorry that it bothers me to see these cars get cut up.

67pro-street 10-21-2015 06:19 PM

Almost a year later and finally some progress photos. I consistently work on the car as time allows, but I'm just bad about taking photos and even worse about taking the time to post them. Nevertheless, the floor has now been completely fabricated and finish welded from the trunk to the firewall. These photos don't show the completed firewall, but I will take some more pictures of that this weekend and post them. Although the black firewall in the previous photos looks good, a closer inspection would reveal a 1/4" thick layer of bondo applied by the previous shop.

http://i1012.photobucket.com/albums/...pszbuxvhcp.jpg

You can see in this photo how the inner wheel well tapers out as you go down. Something I just didn't know to account for when originally widening them so i had to cut them apart and make them parallel with the frame. Took some extra time, but totally worth it in the end.
