Jeep Cherokee Rear 8.25

Question- the Jeep XJ's ran an 8.25" rear axle with LSD,
wheel mounting to wheel mounting (w/brakes installed) was 60"
my 66 Cuda's 7.25" dimension was 53.20" flange to flange.. what was the wheel mount to wheel mount length?
Im taking a guess and figuring its probably around 58-59" may 60" as well, but I need someone with a good knowledge of the early valiant/cuda's to double check my estimate...
Reason Im asking- Cherokee's inhabit my local junkyard like rabbits, Pick-n-pull back home sells the rear axles out of them for cheap. My neighbor from back home was there last night and saw a 00 XJ with LSD that just popped up on the lot, and the axle was 150$. Im thinking (oh god, me thinking.... )that the axle would fit almost the same, minus the perches being moved a bit, without having to shorten the shafts.
