Rear axle in 61-63 F-85 and Skylark

I recently bought a 1962 Olds F-85. The 1961-63 F-85 and Buick Special/Skylark are mechanically similar and use a rear axle that is unique to those two cars. Unlike the similar vintage Tempest, it is a live axle. It is not a normal BOP axle housing and the ears for the rear suspension arms are unique, so it would not be easy to swap in a more common ten bolt.

I've seen some references (such as the Richmond Gear catalog) that suggest that the 8.2" gears fit these axles also, despite the completely different housing design (for example, there is an o-ring seal on the rear cover, instead of a gasket). Does anyone have any additional info on these axles? Is the carrier also compatible with the 8.2 axle? Thanks.

I have never been inside one of those rear ends so I anything that I could tell you would just be guessing. I know where a Buick version of that car is and someone has swapped the rear end in it with a later model. The original rear end is laying on the ground beside the car.

Joe, I just sold a '62 Special. I did have the cover off the diff while rebuilding the brakes and removing the gas tank (was under there anyway).

I can recall that housing being WAY to small to handle the 8.2 diff.

Sorry.

Yeah, thanks. I've since found out that these axles use 23 spline shafts and are apparently weaker than the Vega axle, so it's time for a swap.
