Also in case you didn't know 68-72 Nova, Ventura, and other GM X-Bodys will bolt right in, and of course 68, 69 Camaro. Might be cheaper to look for the X-Body subframes because as soon as you say first gen Firebird or Camaro a lot of people think they have gold. Also 73, 74 X-Body will work with a few easy modifications.
