trying to rebuild my rearend. Its an 8.2 10 bolt and i'm having nothing but trouble. bought a posi unit on ebay wrong size ring gear bolt holes. bought a bearing kit for 8.2 and the shims aren't right and neither are the pinion seal or nut. I bought the chevy stuff not the BOP so I'm not sure what the issue is here unless someone put a BOP 8.2 in my car b4 I got it.
