Spline count and axle size

Hey guys, I heed a little help here.
I'm about to order new Tilton clutchplates for my MFR tranny.

As the thread title says: what is the axle diameter and spline count?.

Measuring my allignment tool its, 23mm and 22splines. Only problem is that i can't seem to find that size anywhere.

Its a dual 7 1/4" assembly.

Thanks
-Kim

Same input shaft size as an FC turbo / FD?
It should be 1" x 23.

^^ K thanks, but I guess that Turbo and FD's has one more spline than 'NA's.
I counted several times, its 22.

Non-turbo uses 1" x 22 clutches, Turbo II and FD uses 1" x 23 clutches.
