99-05 6 speed tranny output shaft splines count
 

Hi, I just want to know how many splines have the driveshaft slip yoke or the output shaft of the transmission.
I have a 6 speed from an s15 and I need a slip yoke. I know the 2 transmissions have the same internal but I can't find any information on the spline count of miata 6 speeds transmission.
