New 12 bolt
 

When I was down at the Crusin the Smokies back in early May the pinion nut on my 8.5 10 bolt backed off
I already had this rear built twice.
So I had this 12 bolt from a 69 Impala sitting down in my basement ans I took it to a friend of a friend and narrowed it and put moser housing ends on. It has a Tru trac carrier with 3.73 gears moser 33 spline bolt in axles.
