well no dice with this one.
found a picture of your guys bolt pattern
still, i wonder if its possible if the quaife for the Super 44 will fit in the grands rear end.
For whatever reason our 5.9L and lifted 5.2L jeeps on big tires seem to chew up the Dana 44 rear ends big time. I only have 55k on my rear end, 12k of that is from me and the carrier bearings are already shot. I'm shooting for around stock viper horsepower by the time I put on my ported heads, cam and a medium sized nitrous shot. (125-150).
