SO I ended up buying the Jeep.
I got the trans pulled out last night and pulled the cover and there is some surface rust on a couple of the gears, and there is a LOT of slop in the input shaft bearing and where the input shaft connects to the main shaft. I have decided to stick with the 4 speed, but I am going to replace the clutch, linkage, and all the rest while I'm in there. The local trans shop wants $550 just to install the bearing and seal kit (unless it needs something else in addition). I still haven't decided if I should try this on my own. Other option would be to buy one off Craigslist or something, I found one not too far away for $400. I feel like I could probably do the rebuild myself, but I really don't want to mess this up.... Any advice???
