It sounds straightforward but it's a pretty complicated task. You have to completely disassemble the transmission to get to remove the input shaft. I posted a how-to on here a while back detailing the process per the FSM.
A good local standup guy (in Northern VA that is) is selling a NA FC trans with the Miata gears on it. I don't want to cross post threads, but if you are interested, I can get you in touch with him (or pm you his FS thread)
