You're looking for cheap parts because you have no money and you want to do a transmission swap???
Cheap and reliable tend to be mutually exclusive. First step is to read the Manual trans conversion document by Huck in the "How To" locker. That's the cheap way. The expensive and easier way is to get the kit from Small Car. Not cheap, but easier than doing everything yourself.
I'm slowly converting mine now. I have a lot of experience and a great set of tools ("my dad's a TV repairman" -name the movie trivia geeks). This isn't something to take on over a weekend unless you've got some capable and talented friends.
