Wow. What the heck did you DO to your tranny to wear it out? I've got 204,500 miles on my DD (95 4-door), and the synchro's are a LITTLE bit iffy, but it's still working like a champ. My trail rig (95 2-door, only has 136,000 miles) needs a new shifter sheet, but it was bad when I got it, back in 2002.
Anyway, a rebuild kit is only around $100, if I recall correctly.
