M&W parts

I have seen many threads on here about the m&w balers and some of their issues. I am absolutely in love with my m&w, but it's all I have ever used since I was a kid. Also it works great for our application. My concern is that I am struggling finding parts for my 4590. I can find the usual wear and tear parts, but I am in search of the rubber-coated net wrap roller. My father upgraded our farm from a 1987 m&w 1500 (which I must add still operates perfectly) to the 4590 only because of the net wrap capability. Only issue is all of the rubber coating has fallen off of the roller. Any advise (other than get rid of my M&W) would be greatly appreciated!
