I plan to swap a fresh 20r and a new clutch into my '80 4x this weekend, and was wondering if anyone had any quick info or advice or rules of thumb before I get started. I have a 20r from a 2wheel drive, and I already plan to swap the oil pan and pump, and I'm picking up a factory toyota clutch set. I don't have time to really search the archives for info, so any thing helps guys! Thanks, Matt
