8.8 swap

When you shorten the long side the 8.8 ends up being 56-5/8 from wheel mount surface to surface. I think it's about an inch wider than the stock rear but measure your existing one to make sure.

You'll end up taking 2-7/8" off the long side.

Stock A body is 57 1/8" wide WMS to WMS, so you are 1/2" narrower with the 8.8 cut to 56 5/8".
