Which body for best performance?

64~66 val with a post, all glass front clip, throw in some J-bars and lose the innder fenders if you're feeling frisky and have the fab skillz.

continue on that trend and keep getting skinny with an alum. radiator, alum heads & intake, manual steering. then adios all the heaterbox junk.

add back in some subframe connectors, radiator support stiffener and upper fender struts as well as the torque boxes front and rear.

that would be crazy light and super stiff.
