I have a Posi rear from a 1988 Pontiac GTA ,,, I'm only selling the diff no brake calipers etc. I was told it was 3.08 but can't be sure, however I do know it is a Posi guy I bought it from demostrated it before he took it out.
I am looking for $280 or best reasonable offer, no low ballers, don't waste my time. I don't have pictures but I can say this much and believe me it's happened , if you don't know what a differential looks like by now you shouldn't be working on any car.
If interested send me your email and cell number and I will be sure to get back to you.

Please note this is a used part and no warranties are implied, sold as is and all sales are final , NO RETURNS.
Diff is located in Woodbridge New Jersey just two minutes from Outerbridge
