CMC subframe

are you sure it's the body that is the issue?  adjusting the rear suspension one side can totally change how the car sits front/back/side to side.

i have adjustable rear spring plates and tweaking them a little does all kinds of cool stuff.

the front support under the gas tank can easily be adjusted too.

if i had to guess (without looking at it), i'd say the suspension was out a little front and or rear

My '89 CMC came with the "deluxe" pre-assembly package - doors were mounted.  The subframe was also mounted. 

I looked at the 1980 CMC build manual in the Library here and it shows mounting of a separate subframe.  

I just looked at the orginal bill of sal and it states it is a speedster c for $6995, so I have to guess that was not the deluxe kit? It has all pop rivets holding the body to the subframe. Is it safe to say it was riveted by the original builder and it almost looks like it was not "square" when the body was riveted to the subframe? The head of the rivets are the size of a quarter.

Thanks for the suggestions so far, I will check again to see if the front or back needs to be adjusted.

I was going to sell this project and buy a completed speester, but I recently missed a deal on a great looking speedster. Now I have the "drive" to complete this one.

Mine is CMC factory FG body mounted to steel sub frame and it uses those large rivets and some type of bonding agent.  I'd look first for other reasons since suspect CMC would have a pretty precise jig to mate the two. My invoice has separate line for "pre-assembly package." 

Thanks Wolfgang, that is what Mango recommended also. This bill of sale doesn't have that line for "pre-assebmly package. I will look for other reasons then.

Thank you guys.
