For the kind of driving you do, I would strongly recommend a Eaton TrueTrac limited slip. This is a excellent posi that does not have clutch packs to wear out and you run just regular gear oil with no additives for the clutch packs found in other limited slip units. The TrueTrack uses a helical gear design. The g80 was marginal at best even when new I would ditch it. I have a TrueTrac in the front 10 bolt in my 81 k10 and it has been flawless and I wish I put one in the rear of my truck instead of the Detroit locker.
Rebuilding a rear end is not a task for beginners as you do need some specialty tools such as a dial indicator. I would strongly recommend you take the axle or truck to a shop to do the work. It is possible to do yourself but like I said not for a novice mechanic or beginner.

The TeueTrac is actually one I had been looking at already, and I think you just solidified it for me.

Does the above look correct for my application?
As far as taking it to a shop, I really want to do this myself. The whole point of buying this truck last year was for the learning experience. I’m fairly mechanically inclined, so I’m confident I can get it done. Although it will probably take me waaaay too long to finish it correctly
