Hey guys, ive got a few questions. I found a 71 Mach1 today. The dash vin says its it a 429 SCJ according to my decoder. Where else is there to check this on the car? Is there any place else the vin is on 71's? I know about the spots on 64-70 but not on the 71-73. Thanks. Also, what do you think I should offer the guy? Its missing the engine and trans but the interior is all there and pretty good, and the body is pretty straight.
