Where are you located, fill out your location in your profile. You can hit up Gary Ramadei in Conn, or if you are close to Texas hit up Mike Dyer or use a vendor like Bairs etc.

Put some GM posi additive in first, before you pull the rear end. It might be the posi clutches making the noise.

I had the same problem on my 77, If your lucky like i was there isnt really much damage, if you drop your rear end and open the back cover, there is a snap ring and the end of each yoke on the inside of the Diff. I had a busted snap ring on mine and after i replaced it, the pop was gone.

Missing snap rings dont cause pops. Maybe you should check the snubber bushing if its making noises when going from first to reverse.
