Well the only one I'm sure that matters on here is the Z28 78. I still have no idea what shape it's in, but it was a cheap good shape body, and a 66 Mustang was the other buy.

But does anyone have any advice on the build like what to really look for as far as the body before I cover it and build on it?

 

Hmmmmm. Got any pic's of he 78? What trim does the 66 have?

 

Welcome to the forum, post up some pic's of both if you can.
