I've been needing to rebuild my rear for some time. Nothing fancy, I don't need a 12 bolt because the car don't see the track or slicks. Just a new set of 3.42 gears and a posi that isn't worn out.

Then I find THIS on Ebay. If it is what they say it is, I figure I can't go wrong.

 

With no track use, that should fit your bill just fine.

Let us know how it works out if you purchase it!
