What Posi (limited slip) for my Differential
Hello, I want to upgrade my Differential with a posi butI´m not sure if it fits.

I know there a different Differentials - 8.2 and 8.5 inch. But what do I have?
I only know: I do have a ten bolt cover
Does the posi fit?
Thank you

In the 66 Cutlass if the rear is original it would most likely have the BOP 8.2 rear. The one from Summitt appears to be the correct unit for that rear if it lists 1966 as included. See notes also about ring and pinion gears able to be used ...

I ID-ed your rear diff picture as a PONTIAC 10 bolt 8.2 rear end which is common to be in a 66 67 Olds.
The unit will fit 2.93 3.08 or 3.23 ONLY ratios. 113 (auburn) end three digits will fit the 3.36-4.33 8.2 gears.
I can beat these Summit prices all day long and the 3.36-4.33 we can get you as Eaton posi better than the Auburn...
3.55 3.90 gears we have on the shelf also. All 8.2 Pontiac gears are a bit pricey again sure I can beat the Summit prices up and down.
Look on the edge of your ring gear to find the stamped in numbers...List them and will decode the ratio for you. Jim
