62-63 B rear
64 Max wedge

The list regarding lengths in that geocities link are wrong

pretty sure this is a 64 rear end....and the old man that runs this salvage yard thought this might be the rear end to his brothers old max wedge car.....is this possible. Wouldnt a max wedge rear end be worth quite a little bit of coin
