Hy Guys, the stock mounts for the V8 option were not installed on the frame unless the truck left the factory equipped with a V8, but many vendors sell a kit to convert a non V8 chassis into a V8 equipped chassis. The horseshoe shaped mount didn't start until the sixties. The bellhousing would have to be an iron truck housing from 55B to 59, or 63 to 68? (60 through 62 were hydraulic clutch equipped with the throwout arm on the right side of the bellhousing), hope that helps.
