Ford 1910 pto shaft

I have a mid 80s Ford 1910 4x4. We use it on our family run small golf course .We have had this old workhorse close to 30 yrs.. About 2 years ago the PTO shaft fell right out,while we were blowing leaves in the fall. At the small end of the PTO shaft there is a small needle bearing. This bearing failed, causing the shaft to wobble and the outer clip to fail because it was now taking all the torsional loads it was never designed for. A close inspection of the PTO shaft showed that the PTO shaft is pretty heavily worn where it rides in that needle bearing. My dealer had all of the bearings and clips I needed however they said that PTO shaft is no longer available. So I threw it together with a new bearing and hoped for the best.. II got about a year and a half out of it. I was hoping a member here might know a dealer that has one laying on the shelf still. If not it looks like I'll be replacing that bearing every year or 2. We put about a hundred-200 hours on it during leave season which is just starting up this week. It just broke now with the brush hog on it.. If anyone knows where I can get a PTO shaft for this machine please let me know so I can arrange payment and shipping thank you very much.
