Turns out they had already scrapped the car. Found another 929 booster/MC somewhat locally and went to check it out this weekend. Looks to be in pretty good shape but the car was at the bottom of a "stack" of three cars. They're going to pull it for me over the week and I'm heading back up next weekend to pick them up.

While I was at the scrap yard I asked if they had any Miata transmissions lying around. I ended up coming home with this:



Miata transmission without tail housing:



Miata bell housing removed:



Side-by-side with my stock transmission. I wonder why the Miata transmission doesn't have the huge harmonic balancer on the output shaft.





This is about as far as I got as I'm unsure how to proceed. Everything I've read on the subject just says "swap the 'guts' and modify the input shaft." Not very descriptive. Do I need to swap the output shafts to keep the harmonic balancer? What about the gear housing? Is there an easier way to remove the input shaft than what's outlined in the FSM? Whatever the end may be I plan on cleaning up the housings and painting them and replacing all relevant seals.

Lastly, here's the driveshaft bearing in my tail housing:



Is the bearing usually this color or is the bearing toast? FWIW, the bearing on the Miata tail housing looks similar.
