I rebuilt mine 6 years ago in the kitchen using a 3lb hammer, some wood blocks, and an adjustable width stand I made out of the metal legs of my ikea desk and some all-thread. The proper diameter pipe that just clears the main shaft diameter is a useful tool for driving components off and on the shaft in lieu of a press.
I had a thumping coming from below that I first though was the u-joint but once I changed those I realized it had to be either the front or mid plate bearing in the trans.
At the time I used some videos of tear down and rebuild of a Muncie by Paul Cangialosi, which largely goes together the same way. Since then he's done a tear down and install vid for the Richmond Super T10.

I bought the rebuild kit from his site,

Richmond has a great exploded view in their service manual

Lots of this info and more is in this book (also by Cangiaosi) but i was able to find some critical passages along with other info online so I didn't buy the book.

I'd never opened a transmission before and I felt like i had invented fire when I got it all back together. Real Castaway kind of moment. Good luck!
