I am going to hold out for a 31 frame, if I find doors I'll let you know! I too plan to use all gm-chevy parts. I have a 54 Chevy that I'm putting sheet metal in it now that I have original frame but I didn't have any of the suspension parts. I sandblasted the frame and epoxy primer in it. I put a set of posies super slider Factory replacement Springs that have a 3 inch drop with a lot lighter spring rate. I did buy a Mustang 2 front suspension kit because I'm going to use it for my daily driver and my wife says she wants to drive it too. I box the frame and C notched it so I put a rack and pinion in it but it's manual. Here's a few pics of the 54. And of course it will have a big block chevy in it with a 700r4. Has rear disc too.
