Dynacorn vs DSE tubs
 

I have been looking at getting tubs for my 67 Firebird Convertible... but find conflicting info. I was going to get DSE tubs... but found a reseller of Dynacorn tubs (DYN-1041FD&GD) that states that these tubs do not require you to notch the frame...

Anyone with Dynacorn (DYN-1041FD & GD) tubs?... did you have to notch your frame just like DSE's? Being that I have a convertible I figured it wouldn't hurt if I could leave the frame rails alone...
https://lh5.googleusercontent.com/-Q...61041GD_pu.jpg

If you don't have to notch the frame then the tubs aren't as deep as DSE's. And if that's the case, what's the point? It's only a little more work. The tubs from DSE are well worth the money and I highly recommend them.

2nd that!

I have been thinking of doing the DSE's... only reason for looking at these.

1. It is a convertible and I have been hearing left and right about how convertibles flex so bad after being tubbed... so I figure without cutting the frame rails it may give a bit more strenght to the car.

2. cost... these are less than half the price of the DSE's

3. I think I will be running a 305 or 315 rear tire... so don't now if I need all the room the DSE's give.

I would go with DSE or not go through the hassle. Also if you plate the frame as DSE recommends, its as strong as stock or probably even stronger. I say go with something thats Made in USA, proven to work, and also somewhere you can call and get help. Look at it that way and its a deal.

I am trying to buy as much as I can thats made here in the good ole' USA even I have to postpone and save more. Im tired of this non-fair trade crap, etc. Sorry to rant...GO with DSE tubs and you'll be glas in the end.

Truthfully if your trying to mini tub your car and are concerned about 350 dollar tubs, I would rethink what your getting into. The tubs from dse are a no brainer but that expense is not too bad compared to what it will cost after the tubs. Good luck. Mini tubbing really is great.

What Stuart said ^^^ If you are trying to save a few bucks but you want to mini tub you may want to check out how much you are really going to spend, and I'm just talken with the rear suspension. Also I do not think you can get a 315 in that tub on a 67. I think DSE says on a 67/68 they recommend with their 3 inch wide deep tub a 315 so you man want to check. Good luck with your project. And yes mini tubed 1 gens are sweet.

Yes... you guys are right... I have been leaning towards the DSE route to begin with... I will be going that route.

I know trying to save a few bucks with the tubs seems a bit odd... But I do know how much suspension can cost... I already have purchased the Speedtech front subframe package... and have been saving up for their rear torque arm system. This is proving to be an expensive hobbie:faint: But I am lovin it!!:willy: I guess I was thinking "a penny saved is a penny earned"

But you guys are right... why not buy USA parts when I can... lord knows we have to buy enought from Taiwan. :rolleyes:

DII vs DSI mini tubs
 

DII vs DSI mini tubs-
Has anyone installed these on a Chevelle? Wondering how much additional effort to stuffing these in a gen 1?

I'm with these guys, support an American company instead of Dynacorn and their made in Chinese crap.

buy USA made when ever and as much as possible its best decision any way you look at it.:thumbsup:

Don't know about Dynacorn, but DSE doesn't make tubs for a Chevelle. Or are you asking has anyone installed the Camaro/Firebird ones on a Chevelle? I sure wished DSE did make them for a Chevelle. I called them a while ago and asked them if they even had any plans to make some for a Chevelle and they said no.

ABC Performance said they are close to releasing the 68-72 chevelle mini tubs.

http://abcperformance.net/mini%20tub%20kit.html

I hope "close" is real soon, because I definately need them running a 20x13, 345 in the rear.

I used a set of the oer mini tubs on my 67. They were prebuilt minitubbed wheel houses for '69 camaro but I just replaced the 69 outer panels with the 67-8 I had.

I haven't rolled the fenders yet but mocking up a set of wheels gives me 14" of space. I'm planning to run 315's so I'll have plenty of space.

I didn't see the DSE tubs sold separately, but if they come with instructions and templates that will be the way to go.

Everyone seems to compare at the 12 o'clock postion. I have the dynacorn tubs on a 69 camaro which measure at 10 o'clock 13.5" - 12 o'clock 14.5" - 2 o'clock 14". It looks in pictures that the DSE tubs cut into the frame rails more. Mine only goes about half way (the narrowest part of the frame is still 1" wide). This is where I think the main difference between the two are at the 10 o'clock position???

I'm curious what the DSE tubs measure in the different positions. If someone with a 69 camaro and DSE tubs could take a couple minutes to measure, then everyone will know the difference.:thumbsup:

Although this thread has been napping for 3-4 months I am curious if the Dynacorn tubs mentioned are the same as OER or different?

At the end of the day the DSE may well be the way to go especially if the novice like myself wants some advice through the install or wants to jump in armed with templates.

I figured I would ask because Summit Racing was on PowerblockTV awhile back promoting the OER ones for a First Gen Camaro. I can't tell you off hand which episode of Musclecar it was during because I dvr them and rarely take time to watch them.

What about the Chris Alston Chassisworks tubs. Plus you can get all the metal pieces for when you notch the frame rail. Anybody try these on a
69 Camaro?

John .... I just bought the kit for my 67 and the mini tubs don't fit for crap :bang: :bang: See my thread with the pictures (page 50)or the Imageshack link below, I'm working with the sales people now .... we'll see!

I found out that the close out panels are for 68-69 not 67's ..... that would be nice to know before ordering.

GOOD LUCK !!!! Should have just bought DSE and made my own close out panels WHICH I have to do anyway .... RRRRGGGGGGGGGGGG!

Sonar Chief,

Thanks or the feedback. I still need to order my mini tub.

Looks like it might be DSE. Is the problem you are having just because you have a 67. Are the people with 69's having the same problem?

Any word rom them yet?
Thanks for the heads up.

John

DSE tubs
 

I installed the DSE tubs in my 67 and they fit awesome. Still had to play with the close out panels but they fit real well and were worth the money. I woundnt waste your time with the cheaper variants, it will cost you more in the end.

John,
Our tubs fit GREAT in the '69! Sonar Chief is experiencing some unique issues with his car which our head tech guy and Chris Sr are helping him to resolve. I will be sure to post more information on this subject later since it was brought up here.

If you have any questions about our products, don't hesitate to give me a call at Ext 247.

~Carl

Does that imply that they don't fit so well on the 67.? :headscratch:
starting to cut..& have your product..

What might I encounter?

Carl,

Thanks for the reply on how the fit is with a 69 Camaro.

The reason I was looking at your kit is because of the completeness
of the kit with the closeout panels. The closeout panels fit a 69 correct?

Thanks
John

Regarding the '67: We are waiting on some dimensions from the customer who is having the issue. Chris Alston Sr left him a message earlier today. I'll update this thread once his issue is all figured out.

Yes, fit is great on the '68 and '69!

Mini tub update!
 

Just off the phone with Chris Alston Sr ... which is awesome service A++ from me, thanks again.

As Carl stated above the kits were mainly built for the staggered shock setup of the 68-69, my Camaro is a early 67 with non-staggered shocks and the closeout panels are not correct. I did not know that going into this cuz I have never attempted a mini tub installation before now.

I am working with Chris to design the closeouts for my car and these patterns should fit other non-staggered 67 Camaros.

I do appreciate the customer service from Chris Alston Sr and his crew, we decided to wait til my outer wheel houses come in to determine the next course of action.

Thank you,
Michael

Last night Chris Sr. and Michael, aka Sonar Chief, had a chance to talk on the phone about the issues that Michael is experiencing with his mini-tub install. We are very thankful for his help and prompt replies to our questions. The situation boils down to three main points.

1-Frame Rail Closeouts: Michael’s Camaro is a ’67 with non-staggered shocks. The rails are different from the staggered shock cars. This will most likely require one new frame rail cutout to be made which can be used on both side. Michael is going to send us a template and we will send him the new pieces in laser-cut steel. They will also be added to future kits. NOTE TO EXISTING CUSTOMERS: If you have a ’67 with non-stagger shocks, call me at Ext 247 and I will ship you a pair of the new pieces for free as soon as they are available.

2-Are The CAC Tubs actually 2-3/4” Wider Than Stock? Yes, they are. We measured our inventory on hand and Michael measured the ones he has in his possession. They were compared to dimensions taken from stock inners for ‘67-‘69 and everything matched up as it should.

3-Do They Fit His Car? Because Michael’s car does not have the outer wheelhouse this is a difficult question to answer. It’s impossible to say for sure whether the outside edge of the tub is being correctly located. His car has been almost completely re-bodied but there is a possibility the factory wheelhouse support is bent. As the outer wheelhouses are on backorder from his supplier, we can’t determine this for sure yet. However, we asked Michael to measure the amount of floor remaining between the tubs and that measurement is correct. Therefore all indicators point to yes, they will fit.

Again, I want to thank Michael for being available and understanding so we can help him get this sorted out quickly and to everyone’s satisfaction. I encourage everyone to make us your first call when you have a question about any of our products. We have free tech help available from 8-5 M-F and 8-1 on Saturdays. That’s ‘Sunny California’ time, of course. If you can’t get through, leave us a message and we will get back to you ASAP.

Im still debating whether to go the Pro Touring route on my 67 Camaro but I would purchase all the parts I could from Chassisworks. I am really impressed with how they have handled the tub issue related in this thread and then they offered to send any other prior customers with 67 Camaro/Firebirds close outs at no charge... KUDOS

I agree I will be buying my mini tub kit from Chassisworks when the time comes.
Sonor Chief became part of the reasearch and development team for
the closeout panels. Kinda made the issue pretty cool.

Nice job Chris sr, and Carl

Later
John

So this is over a year old. I'm debating right now on which tubs to buy. Chris Alston come with close out panels, I'm not a awesome fab guy, but OK. I like that I can get everything in one stop. But DSE have been around for so long.. anyone else installed chassis works in a 69 ?

Does chassis works come with step by step instructions? Do I need to take my gas tank and rear out, Even if I'm not going to narrow it yet?

Help please

Mike

Chassisworks has been around since 1987, in case you were wondering, but Chris original company was building drag and Can-Arm cars as far back as the 70s.

Here's a link to a good install article of our tubs on a 69 floor pan from Super Chevy - http://www.superchevy.com/how-to/pai...eating-floors/

Here's the set going in Steve Rupp's Track Rat '68 - http://www.superchevy.com/how-to/pro...-tubs-install/

And LSXTV's Project Blank Slate '69 - http://www.lsxtv.com/tech-stories/br...l-over-system/ Side Note: they didn't read/fully read the g-Link install directions which state that the frame brackets are to be stitch welded.

ok Carl you touched on to something here I was thinking about. I have the G-bar set up on my camaro. I had a shop weld it up. I'm assuming I'm going to have to cut some of that back and re weld it.

second, How do I get around the lower control arms not hitting the tires..

I'm going to read all of those articles.

Installed
 

A little feedback from the install.. It all went well, Rich didn't experience any problems during installation, (other than running out of Bud Lite).
Fitment was good, close out panels fit well.
Overall tubs seemed as good as DSE, and vise versa. This is the second car of mine that I mini-tubbed and the parts were both well made.

Just a question are the DSE and Chassisworks the same size?? I thought the Chassisworks were not as wide?? Not sure that's why I'm asking? :thumbsup:

Does the Chassisworks kit now include closeouts that fit the 67?

Are you talking about installing the mini-tub and modifying the bracket on the frame rail? You should just be able to cut it back then stitch weld the new edge together.

Clearance with the lower control arm, on the current version, is increased if you order the offset pivots. CLICK "IMAGES" TAB AT LINK HERE.

They have always fit the '67. There are additional cutouts that we now include which will ONLY be used if you have a '67 non-staggered-shock car.


I like this pic!

I was wondering the same thing.

I am pretty sure both tubs are 2.75" bigger than stock.


John

Carl,

My g-bar is at least 4 years old and looks different from your link. Can I call you directly?

I can confirm that ours are 2.75" wider than stock.

Yeah, my extension is 247. I'll probably have you email me a pic so we can be on the same page.
