My experience was before the internet, so was not too aware of sources for other hand-me-downs. When I grenaded the input bearing I ended up rebuilding my own from the ground up. Replacing a few other items along the way. No kits back then either, just the individual parts.
The great thing about doing it that way, was that not only did I learn how they worked and what made them tick, but all the parts combined cost me $45 bucks! That was a good price for a rebuilt transmission even back then.
I also got two tools that I did not have. And have never needed again unfortunately, but if I do, I've got 'em!;D
That was one sweet-shifting transmission and no more popping out of gear on downhill coasting either. Big bonus there.
Oh, and back then you could still get the bronze thrust washers if you looked them up in the Jeep parts for their Dana transfer cases. By then the thrust washers for the front spindle bearings were already nylon/plastic though.
I think the bronze days were numbered. The plastic seems to last a long time since there wasn't a lot of pressure on them, and they're cheaper to produce by a ton.
Good luck Bulldog. Hopefully your price comes out acceptable for what you get.
