So I've finally convinced a friend of mine to buy an MJ off craigslist, with help from a mutual friend with a lifted ZJ. Assuming it isn't too rusted out to be worth it - specs:
* 1991 Comanche Eliminator
* RWD, AW4 tranny, 4.0L Renix (unless 1991 was HO? I forget.), SUA rear axle, unknown if rear axle is a d35 or c8.25
What I'm thinking we should do to it:
* first thing: transmission lines need replacing. No big deal, a hundred bucks at NAPA or 65 at RockAuto if it'll last long enough for them to be shipped.
* convert to SOA using my old rear c8.25 at the end of the month after the all-you-can-carry at Hollands Junkyard. I think this will net around 3" of lift probably?
* convert to 4wd and lift the front at the same time, using my old d30. I have a spare 21 spline aw4 that was given to me, if I'm correct, this should mate perfectly with a 1991 transfer case from a junkyard. Am I wrong? Is 1991 23 spline? I'm constantly forgetting whether the switchover was 90-91 or 91-92 on that.
What I think we'll need to do this:
* new aw4 (I might have one) with the different tailhousing, or swap parts over. New aw4 is easier.
* a 231, obviously - should match the aw4 spline count and have the pre-96 tailhousing for the slip yoke.
* a d30
* a normal front driveshaft from an auto XJ - is this the right length? I'm pretty sure it is, since MJs are the same from the seats forward and a 4.0/aw4/231 is going to be the same length in XJ/MJ.
* a new rear driveshaft for an auto 4wd MJ, possibly lengthened - I can get one out of a manual 4wd MJ with a d35 SOA, I'm worried this may not be long enough since it's manual instead of auto, but it might be longer due to the d35 pinion being shorter? I really don't know.
* front coil lift installed at the same time as the new front axle to match S, not sure what yet.
* maybe a new transmission crossmember. Not sure. Will a stock aw4 4wd XJ crossmember fit?
Thoughts, please... ESPECIALLY on the rear driveshaft length, tranny spline count, and crossmember. Those are what I'm most worried about.
EDIT: all brake lines will be replaced immediately. New bolts will be procured for every part of this install, I hate dealing with rusty bolts and worrying that they're going to break off and leave me SOL.
