I have 9bolt rear right now with 2.77 gears, I recently bought some 3.27 gears for it. I bought a used posi that is in great condition and the ring and pinion look really nice too.

I was looking on this page here and have noticed that they have alot of 9bolt kits.

My questions is, which one do I need? The new gears will be placed in the rear under the car now, it has about 139k miles on it, and it doesn't sound too good, I think the posi is bad. I do plan on getting axle bearings, seals, and ring gear bolts. Do I need anything else?

Thanks guys.

 

I just bought the master overhaul kit from randy's ring and pinion. Should be installing it next week, but it looks like a really good kit.
