If the a15 is the same i could find that more easily from a vanette, but not sure about the 24 spline input dough...

E15 uses the same clutch disk as A15. No difference except for the E15ET turbo clutch & the 4WD clutch.

The automatic driveshaft and the 63A 5-speed driveshaft are exactly the same.

I will try the e15 clutch plate and regarding the tailshaft i think i have to shorten a little bit isn`t it? I`m also planing to use the a12 pressure plate

Yes, it is 180mm diameter, spline is 24T x 25 mm

A14Force, are you says you can use the A12 flywheel with 200mm clutch, if you re-drill the flwheel for a larger clutch cover?

But i will use the A12 flywheel, so i have to use a 180mm one, i bet the one you have your your garage is 180mm isn`t it DDgonzal?

The B210 5-speed uses an L-series clutch, the small diameter one from the L14.

I have a new clutch disk in my garage I can measure it if you like.

While it's apart, I'd reccommend getting an engineering shop to redrill your flywheel to take a 200mm pressure plate from an L series. Then you can just get the 200mm clutch plate from the L series too, which will fit the bigger input spline of the 63A box.

Then you get a big strong clutch that wont slip to go with your big strong gearbox.

I know the b210 auto tailshaft has the same output spline as a 63a box, so it's just a matter of getting it to the right length. I've also been told once that the E15 clutch plate used the same gearbox input shaft spline as the 63a box & can be used with an A series pressure plate to make it all fit. This would probably be easier to find than a clutch plate for a gearbox that wasn't sold in Portugal, even if it's technically the same part. Might be cheaper,too.

Mine is from a US 77 B210 and is a five speed. Now i almost have all pieces to make the conversion from auto to manual, i read here that the propeler shaft is the same as the automatic isn`t it? I will put the A12 flywheel and need the b210 clutch because the spline is larger. I was thinking about the one from datsun b510 but is wider! I will have to buy one from rockauto...

No, not all are doglegs, and some are even 4-speeds.

The 63-series gearbox for A-series engines are all dogleg 5-speeds. The #1, #2 or #3 castings are just variations on the same thing.
