Just my 2 cents here. I would never buy an empty used housing and try to fill it with parts. I hate when I have to rebuild an axle from scratch. Things just don't go together the right way. And you will end up trying to find stupid little things that will make your build take days. Like bearing caps that don't go together, or c clips, or a carrier that doesn't fit the gears. Or something as little as pinion shims has held up my axle builds for two days. who carries these kinds of things on the shelf? you end up waiting two days for them to come mail order and your build just got pushed off another week.
Get a complete axle and replace what needs replacing, and leave what aint broke alone. I wont even work on empty housings anymore. The last Dana 60 empty housing I got with a box full of parts that were supposed to go with it, nothing fit. It was parts of all different axles put together and I spent days tracking down stupid s**t like shims, seals, brake parts, and bearings. It will make your build go that much smoother to have stuff complete from the get go.
