32 rear springs are curved--I'm not sure about 33-4. I have a rear 32 spring that was under a sedan delivery and has extra leafs in it. I think I have the rear end, too- a 55-7 chev housing with the mounts (not super nice) for the 32 spring. I think I have a late (heavy) model A front crossmember, too. I'll try get pictures up later. Get yer tradin' stuff lined up.
