installed yesterday according to instructions.
in a 69 camaro you use the bolt hole for the rear end snubber to correctly locate the crossbar.
there are 3 holes ?
the piece fits in but the inner edges are about 3/8 away from the frame?
outter edges contact the frame.
ill snap a few pics in the near future once i get home.

I know there's alot of design similarities between the first gen Camaro's and the 68-70 Nova's and most of my experience is with the Nova's. So I would think that the rear subframe on your Camaro would be narrower at the front then it is at the rear by somewhere in the area of 12".

Is the Competition Enginering rear shock crossbar car or year specific?

Because of the frame tapering away... could you have it in backward?

I don't know what tools you have available to you, but if you want to make that shock crossmember work. It seems like your going to need to cut the brackets off with a band saw (or a saw with as little curf as possible IE Sawzal), cut the tubing at the correct angle, and weld the brackets back on. By going this route you will make the crossmember about 1/8" narrower.

Hopefully I didn't put my foot in my mouth. I suppose we will see once the pictures are up.

Dawg, one sugjestion I would do is drill a 1/2" hole in one side and put a sleeve in to prevent crushing the sub frame! You only have to weld the 1/2" hole part! otherwise it will collapse.

?im not following you?
the outside edge of the crossbar is againts the frame.
inside has a gap and crossbar rear edge doesnt seat all the way.
(see first and fourth pic)
hmm maybe a rubber mallet will persuade it

Damn it's hard to type what you know!!???

The reason for the sleeve is to eliminate the the crush on the inner liner.
I would weld a sleeve in the inner potion to stop the crushing of the inner sub frame. That will give you a good surface to put the bolt in.

Try and find what tubing does when crushed! You keep tightening and it keeps getting smaller!

maybe a picture will help. drawing one is basically a cross section of where the bolt goes through. #2 is what happens without internal support. #3 is with the piece of tubing welded in as af2 specified.

The pictures make it look like the right side fits better than the left. Is that accurate? If it is, then I'm thinking the problem is production related (either car or the mount) or maybe the car was hit.

I guess call or email Comp Engineering and see what they say. If that doesn't get you your answers then verify that the rear subframe is correctly positioned... if it is then modify the mount to work.

I'm sure all of this has already gone through your head several times over!!!!
