This is an 8.2 ring and pinion I bought for my Pontiac 2+2 but never put it in. I'm not a differential expert so I'm going by what the guy who sold it to me said. I count 25 splines. Feel free to ask me to do any measuring or picture taking to verify it's identity. Price is $75. Ask for shipping quotes to your area. Edit I have been informed that this gear set is for a Chevy
That GM gear is marked right on the pinion 37-11. That's also what I count looking at the pictures. Do the math and you get 3.36. So that much we know.
you stated the pinion has 25 splines, that would make it a Chevrolet gear set. Buick Olds and Pontiac 8.2 pinions have 27 splines.. hope this helps.
Definitely does, but unfortunately it means it's no good to most people here on V8. In Canada, Pontiac's have Chevy powertrains.
Randy, I didn't get your pm, so I tried to pm you and got a message that your box is full. Since this set fits a Chevy, I will need to pass. Too bad, I really wanted it. Hopefully you can find a chevy guy that needs it. Good luck! Thanks, Doug
