Since AMD discontinued their '69 subframe I figured an attempt at salvaging the one I have was in order. If nothing else I figured I'd learn more fabs skills.

I think there's hope.

The current plan is to install a piece of 6 ga. in the cross-member with two vertical risers to eliminate any jack damage.

Constructive criticism and other abuse welcome. :thumbsup:

It looks like you got a good start on it.

Looking good Sieg

Just straighten the piece you cut out -- now that you can work on it - and weld IT back in. Drill a nice hole in it in a couple places --- before you weld it back in -- locate and drill the other "side" (since your bit won't go thru both pieces with the big gap).... and when you weld the piece back in - stick a couple pipes (tubing) in the holes to span the gap - weld them in and you have your strength for the jacking

So here's a pic of a piece I did on a crossmember -- for a different purpose (to pass a fuel line thru -- but similar to what I'm talking about.....



Punch your hole

Trim your tubing to dimension:

WELD IT IN!

I like the tubing trick. :thumbsup:

I don't like trying to make this a piece of my car! :willy:

When I take it to the scrap yard they'll probably laugh at me. :D

Couldn't you get a similar effect to the tubing idea by putting a couple plates perpendicular to the crossmember? They would be standing vertical. Each plate could have a shallow tab on it which would go in a slot cut in the cross member.

Buzz it in and then grind it smooth. You would be left with a box within a box so I would think it would be quite strong, and not all that hard to do.

That's the plan Robert. :thumbsup:

Besides my odds of making a good straight weld are much better compared to a round one. :D

Take good pics. I might decide to copy that idea.

What else do you have in store for this sub? I would be tempted to sandblast inside of it while you have it open for surgery... but then I live in the "Rust Belt" and despise the stuff wholeheartedly.

My car is pretty clean overall but I want to erradicate the nasty red stuff from the sub I am going to use, inside and out. It could be contagious.:_paranoid I wonder if it can jump an aluminum body mount?:lol:

Stopped by the repair shop this afternoon:

It could be worse, like this guy who came in to get an estimate to repair his girlfriends truck after he put two 7mm Mag rounds through it sighting in his dear rifle this weekend.

There were two 7mm holes 1" apart on the inside rail. Those guys sporting the decals got nothing on him. :rofl:

nice group if he was 400 yards away. :yes:

Be sure to square that sucker up and brace it before you do the final welding.
