Just purchased ‘98 Jeep Grand Cherokee 5.9L

I LOVE ZJs, reminds me of my beloved '93 XJ Cherokee. 4.0 straight-6, 5-speed manual, part-time 4x4. Bought it in 2010 with 180k miles and it was a cream puff, my guess a former gov't fleet vehicle as it had ZERO options besides the driveline setup; manual windows, manual door locks, no A/C, no cruise control, nothin'. It was my daily driver for over a decade then I finally got my Buick; only a few months after that it got rear-ended and totaled. I was so bummed, I had planned to finally build it into a serious off-road rig. At least I was able to buy it back from insurance and gut all the important parts to hopefully some day put into another one.
