It would be far easier to get an 74-77 MPC Camaro. The only caster who made them has shut down. You could also try e-bay "resin" but I have not seen any in a long time.
They work weel with a coat of acrylic gloss clear first the the decal and then a coat of flat acylic clear to seal it and give the tire the correct shean. I vote for tire decals.
I just checked my Shebly Series 1 and it has the rear mounted transmission like the C5/C6 Corvette. His best choice is to modify the one in the Monogram 84-96 Vettes.
