Here's my '88. I did a 4.0 5 speed conversion this past winter. (it was a 4.2/automatic)Installed a SYE in the NP231, and a Tom Woods CV rear driveshaft. I picked up the wheels and tires from a co-worker this past week. They are 31x10.50-15. No lift and they fit. I just installed a Posi-Lok for the front axle today.
