When I moved to the city last month, I had to dump all my tractor parts. Sold the bulk to a tractor repair shop (one man show) for pennies on the dollar, but it was better than sending them to scrap...about the same money but at least they're still available for people who need parts.
Among the items I sent to him were both rear axle assemblies for a Ford row crop. He also got a good 5 speed tranny. If you need his contact info, let me know. He repairs tractors and also sells parts.
My email is open.
