I found the swap to be very straight forward. The front axle is a bolt in and I was able to use the stock front driveshaft with spacers (I had to redrill the toyota flange). Part of the reason is I used the Trail Tough YJ spring mounting kit with the YJ springs kicking the front axle forward enough for the longer 3rd member of the toyota. The rear was easy and I didn't have any vibration from the offset t-case to centered rear axle. I did run a rear torque bar for spring wrap.
I wish I would have kept that rig... HTH
