Need some help locating some rear end parts

[cobra_4]

I need some help!! I've got a good friend who has the rear end of his truck tore apart. He isn't internet savy so I told him I would help him out, but rear ends are not my area so I have no clue what I am looking for. I need these parts and a flat washer of some sort that goes against a bearing? I need either this stuff or a whole kit with it in it or whatever. Can someone point me in the right direction or what I should even ask for? Its a 69 C10 cab but someone has installed a 1 ton dually rear end under it. I assume from some other part we have ordered the rear end is out of about the same year. These are the only numbers we could find on the rear end. 3934635. There is no tag on it. Any help would be great!!

Somebody put in a later model 14 bolt full floater. So grab a year ....say...1976. A decent auto parts store should have those under a Dorman part number. I have the part numbers at home if you want me to post them up later on.
