Olds/Pontiac 9.3 in an A-Body?

I would make absolutely sure that you can get the parts you want for it, AND how much they would cost. I'm betting a lsd for it is almost unobtainable.
That said, it IS a very strong rear, lots were run with welded spiders, and as mentioned above, VERY popular in 55-57 chevys in place of that plastic toy rearend they came with.
