Dave, you may have good luck finding the items you need by posting your request on the yahoo groups treadleon site. Also the list owner, Cindy Peters will be able to help you with the spring, she is our 'go-to' supply person, prices are good and service is excellent. If you can't find an original wooden pitman rod, there are instructions on how to make your own on the treadleon.net site. You have an AMAZING treasure in this machine! I have one but the decals are sadly worn. I'd jump at a chance to get one in such beautiful shape as your machine! Good luck! Carol in Mid-Mich
