I did find a shaft for $50, it's on it's way from Alabama.  It still has the gear, bearing,and hub on it.  I went on ebay and asked everyone with 77 parts 4 sale if they had a pto shaft.  I got 3 responses that had, and one that did not have one.  The person I bought from sent pics and it looked good.  hope I'm not disappointed, should have it tomorrow.  I pulled the belt pulley assembly apart yesterday.  the bearings were all rusted.  I found new bearings for $114  will order them in the morning.  I don't really need the belt pully but I don't have the input shaft cover to go without it, and I did not want to put the rusted stuff back in there.  I think I'll have work for the weekend.  Ken
