I put a clutch in my 1000 back in 2016. This was the first clutch since it was sold new in 1977.
I highly recommend a new driveshaft from Jeff in PA. I sent him the original shaft from my tractor and he made an equivelent replacement. The original shaft had steps worn in it that would have made it impossible for the pressure plate to move.
I have a couple of threads that discuss my clutch replacement:

If you have any questions post on this board. I learned a lot here.
