Ford 8.8 Questions

For those of us who don't want to shorten an Explorer 8.8, is there any 8.8 rearend that is approximately the same size as my '75 A-Body 8.25"? I've tried to compare widths doing searches, but ford guys measure 8.8 wheel mounting surface (WMS) to WMS, while Mopar guys measure flange to flange, apples to oranges. My '75 8.25" is supposed to be 59.25" flange to flange. I want to stay with the 5X4.5" bolt pattern, hence the interest in the 8.8 swap. I'm sure somebody here has figured this out?
