Heh, have fun with that. I tried pulling the T-case off in my wrangler and finally gave up and just cracked it open instead. And the wrangler had a 2" body lift to get up in there with a wrench too.
Personally, I think it would be heaps heasier to just crack the cases, swap the mainshafts, reassemble....but again, that's just one man's opinion.
And I can't help that weekend...my pop's birthday is the 28th and I'm moving on the 1st. But if ya don't get it done and require some assistance the following weekend, I'd be happy to lend a hand.
