Guess I should have checked my notes. There are two 21T servo 5th mainshaft gears, original part number 32340-25500 (unsplined) which was superceded by 32340-25501 (splined). Edit: Ok. Went to those sites. Will be calling them tomorrow. Lots of good info there.

I don't have the box. My customer has it and since he knows exactly what he needs, I assume it is apart. He has been fixing Nissans for over 40 years and in fact bought a 240z new right after they hit the showroom floors. According to my research, this box has only one possible 5th gear, 21T servo style. Price is not the issue since these are Unicorns. I have servo type 5th gears for later boxes, but they don't fit.

This is exactly why my customer called me - He can't find it and I am known as mmerlinn da wizard, purveyor of Unobtainium and Unicorns, even though most of the time I am unable to find them.

According to the customer (local to me) the transmission is an FS5C71A. If I can, I will take a look at the car tomorrow to verify. Here is an exploded view of the gear train. http://www.carpartsmanual.com/datsun/sports-1965-1970/power-train/transmission-shaft-gear/5-speed-(servo) and a view of case parts. http://www.carpartsmanual.com/datsun/sports-1965-1970/power-train/transmission-case/5-speed-2000-(u20)

Does anyone have or know where find parts for 69 5-speed servo-type standard transmissions? I have a customer needing 5th gears.

It IS July 1977 as it cannot be July 1967 (long before W71 series transmissions were made) nor July 1987 (it has crush type synchros).

Not strange for transmissions with crush type synchros. I have sold dozens of sets in the last 40 years and still have 6 sets in stock.

Yes, it is possible to change only the fifth gear ratio. Unfortunately, since you have the crush type syncros, there are only two ratios available, the common one (31x19 teeth, 0.613 ratio) and the rare one (38x22 teeth, 0.579 ratio). I sold both of my rare sets for $285 each in 2013 & 2014, so I cannot help you there.

Cra I bookmarked that site. Superficially it looks like exactly what I am looking for. Thanks.

Unfortunately, those manuals do not have what I am looking for.

Thanks, but no luck there. Have posted an ad in the wanted classifieds. Will see if that causes one to surface.

That conforms to my handwritten notes in my Mitchell. Was hoping to find an online resource with the information. No point in compiling a list right now. Probably easier for you to proof my guesses per my reading of Mitchell. Will worry about it later. For now I need to find a good used or new bearing race for first gear (32253-H7300 BUSHING, Mainshaft) for a customer of mine.

I need a good parts list for 79-82 Datsun 210 transmissions showing OEM numbers. Anyone know where I can find one? I have links for most early Datsun transmissions (for example, https://www.carpartsmanual.com/datsun/sunny-1970-1973/power-train), but 210 is not included on that site. The only thing I have now is a 1986 Mitchell book with one illustration used for all FS5W60A, FS5W60L, and FS5W63A transmissions which is pretty useless since the internals are radically different for the three transmissions. The Nissan sites I know about only go back to 1984.

In my neck of the woods, bellville washers are coned, usually with inner fingers, and not wavy. Never heard a wavy washer being called a bellville washer before.
