Ok so after doing some figuring the 8.8 will be around 56” flange to flange as opposed 60-61 on my stock 12 bolt. So I know 5.5” backspacing on a 15x10 will fit a 295/50/15 but will rub a touch. So I think we’re going to put 9” big bearing ends on my 8.8 and probably bolt in axles of equal length. Wish I could get my truck in the garage and get the old rearend pulled out and on the ground to start fitting the new. I think I’m going to do a 8.8 build later once the pictures are taken and done. I need to find some wheels to work with maybe just have a set of steel rally’s built for now!

The correct way to go about this is to purchase your wheels and tires first. Then with them at your desired outside width to fit inside the bedsides, measure the WMS to WMS width of the wheels. Then build your differential to that dimension.
