for the 8.8 I am just repeating what I read in four wheeler a couple of months ago. The fact that '95 Exploders had rear discs is also a plus in my book. Don't know how cheap you could find one of those for though. The following was posted on the XJ-List:

The Dana 35C-rear axle has a 7.5625" ring and pinion and uses 27 spline
axles that are 1.25" in diameter.
The Corporate 8.25" rear axle has an 8.25" ring gear and uses 28 spline
axles that are 1.25" in diameter.
The Corporate is a hair stronger where the splined part of the axle is
simply because it has one extra spline - not *that* big of a deal. Same
size axle shaft.

The Corporate 8.25" rear axle has an 8.25" ring gear and uses 28 spline
axles that are 1.25" in diameter.
The Dana 44-rear axle has an 8.5" ring gear and uses 30 spline axles that
are 1.3125" in diameter.
Looks like the ring and pinion on the 44 are stronger to me...
