Did you find the 77 PTO shaft yet?
  There is a fella, Raymond Harvey, who is an AGCO dealer and he was an Oliver/Cockshutt dealer. He is over in Dover-Foxcroft... that is a ways from Gardiner, but he has a fair assortment of tractors for salvage. I can't remember seeing any Oliver 77's, but it can't hurt to ask. I had his phone # around here and seem to have misplaced it, but if it turns up, I will forward it to you.
