What is the diameter of the T9 input splines and sleeve?

1"- 23 splines, not sure about the sleeve dia, why do you ask??

I want to use a concentric slave clutch on a toyota gearbox. I have managed to find out which Mondeo clutch fits on the T9 so I need to know if the dia's are the same. My gearbox is a 21R or W55 I think.

Oh me as well, I have a W58 Toyota box I'm converting to fit my new 170ST engine...

FWD box split and use the front bit as a bell housing..

My Toyota box shaft is much bigger.. I'll measure them tomorrow and hopefully post some pictures.. hic!

Is this any help.?

why not use a saab release cylinder, they are cheaper!

Also, with a concentric release mech, you don't need the sleeve anymore so you can just get rid of it, that's what i did
