I have a 10 bolt 8.5 with bolt in axles. I believe. 41-15 tooth count on ring and pinion. This is under the 65 GS I am parting out. Non Posi. Curious if it’s worth anything??
Well thats great news. But I already have a 9" under my skylark that im building up. I will probably wind up selling this sometime in the future.
As soon as I get the body off of this (im parting it out) I can look for some number codes stamped on the tubes.
If it's not I can sure erase and strike any digit on there to make it a 71. hahahah Or it could be a late/Early model rear.
Pretty sure the 3 letter codes for gear ratio and Posi are the same for 71 and 72. That would just leave a date code. Do you have a non stock rear Manny?
The one under my car is a 1971 GS350 rear originally. I got it from BrunoD. He might have another, not sure, PM him.
I just picked up 71 olds 10 bolt. All the internal stuff including axles are the same on 71,72 Buick Olds?
Yes, 8.5 10 bolt with bolt in axles, 28 spline axles. The 71-2 Cutlass rear, same as the Skylark/GS. http://www.jdrace.com/content/diff_id/10b85.php
