Well. Crap.
Ok. I'll let you know what I find. Probably won't get a chance to do it till the weekend.
How long should it take (measured in beers) to pull?
depends if you elevate the Jeep of just do it on jackstands. Make sure that if you take the t-case out separately you drain the transmission and t-case first or you'll spill oil/fluid all over the place. if you have a transmission floor jack (or adapter) you could just slide it back together with the t-case, i would still drain at least the t-case if you don't have an SYE, if you do then there's no need if you keep them together. You'd still need to remove the skid, shifters, driveshafts, 4wd vac lines, speed sensor wiring, reverse light switch wiring, vent lines (make sure they don't get stuck to rip/crack). you can get away without removing the starter but make sure you align the inspection cover when you slide the transmission back on (don't ask how i know, same for the oil spill).
if you have everything ready can be done in a few hours, if you need to walk around could be couple of days. Not sure if you need to take the flywheel off or not, if you do then you'll need a clutch centering shaft, don't try to eyeball it or you'll be inventing new swear words (you probably know that already but just making sure).
oh, and when you drain the t-case use the drain plug and not the chain tensioner plug (the drain plug is somewhere on the opposite side of the front output yoke if i remember correctly).
