alternatives to an 8.75- what about an explorer 8.8?

There are several issues with the explorer 8.8 # 1 being that it is 61 inches flange to flange, #2 is that the pinion is 2.5 inches offset to the right, so you`ll have to narrow it on the left side to bring it in line with the a-body width. other than that there are a lot of ratios available.http://www.therangerstation.com/tech_library/Axles.html
