Frame Question

[tomsc4655]

Hey guys (and gals). I am thinking about building a Chevelle and have a vision of what I want to do and need some advice. I am looking to build a 70 model but will also clone a 71 or 72 if needed. My question is about the frame of the cars. Is there a different frame for a convertible than a coupe, and are any of the other A body cars (Cutlass, Skylark) the same frame. The reason I ask is that I am thinking of using one of the new Dynacorn convertible bodies eventually and really only need a basket case of a donor car with a good frame to start with. This will be the Mother of slow builds, but will keep me out of trouble (I hope) and give me something to do. I know me, if I buy a running car I will just tear it down anyway and start over so I’m trying to start from the ground up to avoid wasting any time and money. Thanks for any help and info you can give.
