Maybe someone has one from a B210 5-speed (63 series) and can measure the length it should be?

I think the thrust bearing has more to do with which flywheel you have. I'll take a look at my 63a, (Which is out ATM) and see which one it has

Yes, there are two throwout bearing sleeves depending flywheel for the 56 and 60 series transmission. Actually I think it is not the flywheel, it is whether or not you using the block plate which comes with A14 engines.

Yet the 63 series is different...

Im not sure where the fly wheel came from, it might have even been from a f10 a14.
the plate I used between the engine and the tranny looked to be a shy 1/8" and was the complete one, unlike the automatic plate which was thin and only a have plate.

Im still unclear if i should be lengthening the master rod or loosening it, if it is lengthening it, would shims help?

You should be tightning the rod, to make is shorter. You need play at the pedal.

Datsun 1200 calls for 1 inch play.
B210 with 5speed is about 1/8 play.

OK, I cut off ± 3/4" from the rod.
I have ± 1/8" free play now.

when the clutch pedal is up, there is now a ticka ticka ticka sound.
this goes away with a slight pressure on the pedal.

Do you have the correct 63a clutch slave cylinder? It is self adjusting.

Look at it, if you can adjust it then put 1/8" free play there too.

The slave is self adjusting, I wonder if I should bleed the clutch since I removed the rod from the cylinder.
some fluid came out when i pulled the rod out.

Car was written off, I was rear ended by a municipal front end loader...

No longer an issue.

Keep that gearbox!
Or better yet, give it to me!
Sorry for your loss mate.
