Here's a link with a long discussion and lots of photos regarding the answer to you tire and wheel question. Since all of these vehicles were built with a lot of tolerances compared to the factory specs, there's lots of varations in the placement of the rear axle, so measuring VERY carefully before ordering any parts is mandatory. This should either enlighten you or confuse the hell out of you. :) Hope this helps.
