H052 Parts Source and Brake Parts for 3/4

[f66]

I am rebuilding the Eaton H052 3/4 rear end in my 1966 truck. Does anyone on the forum know a good source for the backing plates and other parts to restore the rear and the complete brake system to original?

Thanks Frank

Not sure what exactly you need for the rear, but all seals, gaskets and bearings should be available at a local "real" parts house that knows how to read a parts book. Chain stores won't be much help. Be aware that some parts are kind of pricey When I recently went through mine I only replaced the parts that were bad after being inspected by a local pro. The good news is if given a steady diet of clean oil those rears will last forever and the stuff like Ring gears that aren't available new are easy to find used. In fact, I just took apart a nice rear from a '66 K20 that I would be happy to share, although the shipping might be a problem.
As far as brake parts, back plates are a used item, but if it's a C20 everything else should be easy to get local. If it's a K20 things can be more of a challenge, especially for the front, But I have managed to find everything, so can help with specifics if needed
As a last tip, if you are tearing that rear down anyway, the best thing you can do for it is weld in a bung for a drain plug. That was the only thing GM missed.
Good luck with the project,
Tom

There is a thread here about what parts from a 14 bolt will work on a HO52. I believe it is in the engine and drivetrain section. Personally, I would scrap the HO52 and install a 10.5" 14 bolt with better gears.
