Got spacers on mine - think maybe 1-1/2...have to look it up.
Technically there is a puck n shackle 2" lift with but the old saggy leafs & springs it's probably just a bit above factory height.
The two door XJ seatbelt is longer/shorter than the MJ - can't remember exact dimensions but it was a little close for comfort so on mine measured the old belt and bought one that was as close as possible - Chinesium unit off of Amazon.
On the bench seat the china unit was almost too short on the female side and had to modify the bracket for the retractor to bolt up properly and still not interfere with trim panel.
I have a 2 door Cherokee will have to look at that again to see the difference but think the retractor mount is on the floor on the Cherokee & on the MJ it's about half way down the pillar.
More progress....
Got the cover (new) on the diff - did a quick tape/spray job and clear coated the whole thing.
Used a couple of studs to stand off the LSV bracket (thanks to The86manche for the bracket)
getting the brake lines sorted - have some cunifer line and ss gravel guards to diy replace the hard lines on the axles....but the ones on the '88 are pretty clean so might just use those.
Waiting on a few more parts - have an airbag kit plan to install but with the shackle lift need spacers for the airbags - those are on the way...
Slowly plugging away at this - collecting parts (it's the little stuff....)
Cracked the cover on the diff - what am I looking at here - PO said something about a Yukon posi - this looks like their Dura Grip LS - clutch style.
Anyone running one of these?
