transmission bearings and seals??

[scrap487]

I'm wanting to rebuild a 4spd d/r out of my lifted wagon... I know a lot of people are going to say its not worth it and just get a 5 spd, I'm considering that also and I may do that too but I want to rebuild this. If for nothing else, just for the sake of getting inside one of these transmissions and having something most people wont care about if I mess it up.

 

I'm trying to track down parts but no luck, I can get the seals but cant get bearings. I can also get a rebuilt transmission but cant find out where the rebuilders get their parts from. Anyone have any ideas?
