I've had lots of problems and rework over the years. I installed a Dana 60 front a year or so ago. Finally got the matching geared (4.56, not great) 14 bolt installed. It's currently sitting on old 39.5" IROKs. It will need a bit of trimming in the rear wheel wells. It's got a spool in the rear that I don't think is going to cut it and both axles will need 5.38 gears to be the way I really want it.
