12 Bolt Cover Olds rear end
12 Bolt Cover Olds rear end
Hoping some one can help me. I have a 1970 cutlass supreme with a 8.5 O type rear end with 2.56 gears. I know this rear end is unique to Oldsmobile but I am looking at upgrading to 3.73 gears and need to know if this can be done without changing the carrier (use a spacer instead). Also if some one can give me a list of parts so that I can price it out it would be appreciated.

Well your not going to get 3.73 as OLDS never had 3.73 in the 12 bolt cover rear. 3.42 or 3.90 is it.
You can with a custom modified spacer ...achieve the 2 to 3 series needs of the ring gear to install into your rear differential housing for the 3.42 and 3.90 RICHMOND aftermarket gears
