There is an online Kubota dealer called Messicks that is very good about selling and shipping to individuals. I have bought parts form them cheaper than my local dealer.

Is there a John Deere dealer that does the same thing?

Might try these guys?

one of their subsidiaries had a part I need for an 80's MF industrial tractor

These folks helped me with some parts, and manuals too

Thank you for the links.

there is a lot of mom & pop part stores that sell old tractor parts on amazon

I have bought some parts from Wengers in Pennsylvania. Good people to do business with. Also, Messicks.
