Chuck's is about the only support for R&P sets for the Timken Detroit axles. Some of the later units are impossible to find new parts for. Good used is as good as those get. Timken bearings should be available. Seals may have to be matched but there are still some Chicago Rawhide seals around. A person just needs the part numbers.

The transmission should be a T8 or T9 4-speed. Ford used them for years. They aren't synchronized so a lot of folks don't like them. There are a lot of them out there,

Some Folks convert the rear end to a Dana 60 or other truck type axle just to get better ratios.
