    If you can find a LeSabre, they use the 8.2 rear. The housing is different but the carrier can be swapped into the Skylark rear.
    I'm not sure what year LeSabre, but 65-67 should be right.

    I want to swap out the whole rear end. I was even thinking of a ford. I can come across a 68 Chevelle rear end, but what the going rate to shorten it?

    You wouldn’t need to narrow it. Your 66 has the same width. 64-65 were narrower for Buick. Chevy was the only one that kept the narrower rear up to,and including,1967.

    Agree with Brian, your only talking about 1/2" on each side wider which is not really going to make much difference unless your squeezing the MAX tire in the back. If you are buying NEW rims and tires wait till you get the rear in then do your measuring and you can make the rim backspacing what ever you need to fit that MAX tire / rim combo.

    Riv and Wildcat are considered full size cars in that era for the whole rear and the size of the rear is 9 3/8 Buick totally different to use the guts.
    1966 9 3/8" rear will also be a weird on as there is a early and late version so the guts could be different IN THAT SAME 66 year...OUCH MORE HEADACHES
