I need a 21 spline shaft

I am sorry our supplier currently does not offer a 21 spline unit, I have requested that they build us a few which we may have mid summer this year!

What is the diameter?

This clutch measures just over 7" is diameter. Thank you

Won't fit inside the shield of my kubota b2601 pto. do you make one that's about 2" smaller in diameter? or where might i find one?

I am sorry but I am not aware of any units that have a smaller diameter. These clutches can also be placed directly on the implement gearbox which might provide more clearance for it's size. The clutch is designed to work in either direction.

what is the dimension from the end of the female shaft to the center of the hole where the bolt connects to the tractor pto

looks to be about 5-1/4" from center hole to center hole Thank you,
