The 60-66 2 wheel drive chevys use coil springs...the 4-wheel drives had leaf springs. The 60-63 frames are also a little different than the 64-66....as far as swiching to an 73-87 chassis, the shortbox wheelbase is 115" on 60-66 trucks and are 118" on 73-87 chassis. I assume the longbox also has the 3" difference (?). You can move axle on the springs etc.... Its a lot of work and math no matter how you go ! Good Luck with your project!
