My book does not show this #......FOUR NEW FACTORY ORIGINAL TRANSMISSION SYNCRO RINGS FOR DATSUN 1200/B110 AND B210, 4-SPEEED TRANSMISSION. DATSUN PART NUMBER 32604-H7300/H9000. .....as fitting a 4 speed 1200 tranny. Maybe it's a superceded #?
Any help appriciated. Thanks

Also do many/any B210 4 speed internals swap with 1200 4 speeds?

I've been looking in the archives too.

My 1200 book shows the following.

32604- H1000 Baulk Ring. This part number is shown to be used for all four gears.
It is shown as item 22 & also item 30 in the illustration, however the item 30 position [3rd & 4th gear] shows that the number was superceded by

32604- H1010 Baulk Ring. The book says that this part is interchangeable with, & therefore replaces, the earlier part, but not vice versa.

That the new part number is shown as a replacement for the older number in the 3rd & 4th gear position only strikes me as rather odd.

This is for the 56 series trans. I have no info on the 56A trans.

That sounds exactly like what I'm looking at. Same book?
Mine has a revised date of Dec '71.
Does anyone have a newer book?

Maybe the baulk/syncro part 32604-H7300/H9000 is wrong for a 1200. Even though the seller states it to fit one.

Thanks dodgeman.

32604-H1000 has been superceded by 32604-H9000.

32604-H7300 has been superceded by 32604-H9000.

32604-H9000 Nissan retail price is $39.80.

These are for the 56 & 60 transmissions. All USA B210s four-speed after 1974 have the larger 60-series transmission.

Interesting that the baulk rings were not upgraded. No wonder they rarely go bad on a 1200, they are plenty tough.

Thanks again DD.

How did you get the newer #'s??????

With the help of a friendly Nissan parts man. It doesn't mean the parts are available ... but it is not too hard to get the part numbers.

Any idea if they will suit a five speed 60A trans?
