Where to get a stock G80 posi rebuild kit?

[TA49-WE4]

Hello I was wondering where I can get a rebuild kit for my G80 posi unit. There's one on ebay: Is this what I need?

eBay Motors: Buick Grand National Posi Rebuild Kit (item 260088227144 end time Apr-12-08 20:16:40 PDT)

Thanks for any help.

GM still sells those clutches. not sure of the price, tho.
get that, and a $100 bearing and seal kit that comes with Timken bearings and a new crush sleeve, and you are good to go.

Crush sleeve has nothing to do with the posi unit rebulid that is on the pinion.

Rebuild the posi unit will be the clutches, springs, side bearings and races. Off the top of my head cant remember if you can get higher lb springs or not from GM

yeah, i know the crush sleeve is on the pinion- but since it's apart, new bearings in the whole rear axle aren't a bad idea, and it isn't a bad idea to have a new crush sleeve around just in case the new bearings change the way everything fits together.

Then you have to completely set up the gears again which is a pain.

yeah, but i can't see why anyone would rebuild a posi and not put new bearings in, and just putting in new bearings could change things a little bit.
it's best to have the crush sleeve "just in case".
