I have a new set of 3.90 ring and pinion ordered from summit last year by my buddy. He ended up buying another rear with posi and gears already set in so he gave me this set. Its for a 8.5 Rear was going into his 71 olds rear. I also have a nice used posi unit.

I believe this is the set he ordered. They are new and I will take 100.00 for the set.

Used posi unit out of a 71 olds rear 8.5 I will take 250.00

pm sent. how is the posi unit. did it come out of a running rear end and would you take 250 for it.

 

posi came out a running car. i would def go through it and make sure its up to par when you take it to rebuild your rear. I would let it go for 200 plus shipping
