1972 TB3 340 Demon

This would make a good candidate for a late-model undercarriage retrofit. Someone here did a late-model Challenger with an A-body skin. Would be much easier than carefully replacing all that carnage.
I’d probably consider that if it wasn’t a 340 car.
I’ve got a 4dr 68 valiant parts car that is nearly rust free. I’ll pull the rails, trunk pan and under seat pan all in one. I think the inner rockers are different so I’ll have to buy new stuff
