Hy 59 Rocket, you will have to use a bellhousing from a truck, they have a single mounting hole for securing to the crossmember a 1/2" nc, the bellhousing from a V8 55B to 68 or there about. You will also have to purchase the mounting brackets for the front crossmember of the frame, these were not put on at the factory if the truck was not equipped with a V8 engine. There are many vendors which offer a complete kit for this conversion, with all the front mount pieces for the V8, hope that helps.
