Welcome to the forum Francis. I can't help you with OEM parts but I may have a suggestion for a rebuild. When I needed new tires for my bandsaw I took the wheels to a belting supplier. The belting that they put on my wheels worked way better than the original tires. I think the same thing can be done with your feed rollers. The belting that I'm talking about is the power transmission type or the type that carries material to or from a mill.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
