Use a later model C4, just switch bell housings, assuming you already have a C4. The post 71 C4s have a better design, and rebuild kits and shift kits are readily available (although ALL C4s are good trannys)If you have the Two speed auto, you will need a pre 1965 C4 bell housing (I have several)and possibly a matching 260 C4 flywheel. A good C4 would be a 302 Mustang II, which had a deeper sump pan and will hold more fluid.
