well i am puting a new clutch in my 88 diesel and in the prosess i found that the input shaft was wore and that the pto and hyd shaft was wore verry bad and the hub that drives the pto and hyd shaft . I found a input shaft and installed it but i am trying to locate parts new oe used 
#1 hub on the crank 
#2 pto and hyd shaft.
the cluthc i took out of my 88 is a 11 inch i done some looking and found that only 88 industral had a 11 clutch my flywheel has holes for a 10 or 11 why would my 88 have a 11 when it should have a 10?
