I was looking at changing just the chunk with the ring and pinion, not the whole rear end housing, if it would bolt to the truck housing. The salvage yard has the chunk that was removed from the '55 car rear end. If that won't work, then my next step would be to find a whole rear end that is the same width as the original rear end with 373 or less ratio or locate an overdrive transmission.
I have the OEM V8 throttle linkage, OEM cross member mounts, front engine mounts, a 14" flywheel, 11" clutch and pressure plate.
