I understand that but the E body cars are not that much different than the Gen 1 Camaro. I used to be one of those Mopar guys & yes mopars 's calling card was being fast! ( But handle like crap stock) My messing around with making the cross member is more of a learning experience than anything else but starting where c5 pickup points are must be somewhere close. Beside who would hack up a 70 convertible?
