Just as a reference:
My jeep has a 2 1/2" lift
1/2" (homemade) T-case drop and 4° rear shims.
It's not perfect, but it is REALLY close.
1 1/2" T-case drop sure seems like a bunch for a 2.5 lift.

That was my thought on the T case drop size. Plus there nuts welded together it looks like. Sure they will never crush but personally Id go with the bar type as Macho indicated. Based off your info you exactly where my 91 is regarding angles/degrees and Im smooth and vibeless. But... after 4 Cherokees with mild lifts each seem to have their own set of issues/vibes etc strangely enough.

If the trans go up 2.5" with the lift, why wouldn't you want to lower it 2.5"? Regardless that mine is 1.5".

I find I am having to correct a lot of things done by the previous owner.

If those spacers are the worst of it you are golden. Surely you have seen what some folks are of capable of when it comes to mods and repairs. ;)
The pinion yoke felt loose, so I pulled the joint and the pinion nut came off with a 3/8ths ratchet. Was never torqued. Ended up putting new Ring and pinion in. Other stuff with brakes not done right. All in the game

Just geometry.
I'll bet you a dollar to a dogecoin you will have less vibration If you cut that t-case drop in half (or more)

Easy enough to experiment with! Well, I had to change one of the shims around, because it was in backwards. Snapped two U bolts so have to wait for them to arrive. Then the skid plate bolt holes stripped out. Guess I will be cutting them out and welding new nuts back in.

So many have relied to my driveline vibration I am not sure where to post this.
Finally got my new u bolts and replaced old ones because they snapped in trying to loosen them. Got the shim (2.5 deg) turned around that was in backwards. Found center bolt was too short to enter axle (replaced). With all that done and the skid plate shimmed at 3/4" she is smooth as can be. Thanks to all for the advice!

Hello to anyone who know if they make a fuel inject intake manifold for a 1988 jeep yj 4.2 and if so, where could one get one? Also, I would like to get two steel full doors.

You probably meant to post this somewhere else….there used to be a kit from Mopar to upgrade the 4.2 to basically be the same engine as the 4.0. It included a new intake manifold. However that’s long been discontinued. You could do the Howell fuel injection kit which won’t give you a new fuel injected intake manifold, but it will upgrade the carb to an electronic throttle body setup that works pretty well.
