Oh yes, the limited slip was a big part of the reason I did the swap! The 2.56:1 peg leg rear end just sucked and I wanted to upgrade. Looked around for a while and the best thing I found was this 3.08:1 diff. I ended up sending it off and having it converted to a limited slip. Normally it's not worth doing that, but since NOBODY makes aftermarket parts for these 65-70 Pontiac B body axles it made sense.
I looked into using a Chevrolet axle... No dice. I looked into having a custom axle fabricated to use the stock suspension mounting points, that was gonna be like $5k.
I'm still wondering if one can cut the axle tubes off the P axle and get an A body 12 bolt center section with stub axle tubes and weld them together. It would take custom axles, but I think getting those made would be doable.
That's on the "someday I'll look into this" list... I would need measurements from an A body axle, specifically the center line to the upper control arm mounts to compare to the P axle.
