65 C10/C20 rear drum to disc

[nelson-ohio]

Since the front drum to disc is going relatively well, I decided to take a look at the rear to see how much work it will be if I want to convert it to disc as well. My truck is a C10 with a C20 frame.

The rear is an 8 lug as shown in the picture below. I didn't get the rear assembly when I got the front end from the 84 donor C20. I wasn't sure if I wanted to do much since the rear looked to be in very good condition.

Do I need to swap the whole rear with a later model donor? What options do I have. There must be someone also did something like this, didnt find any link with a quick search. Maybe someone can point me to it?

Thanks.
