Sorry guys, I don't have photos....I don't even have these machines anymore, I made these more than 15 years ago. But it is not hard.....Find the plastic from Granger, you can get it in sheets or round stock, drill a hole in the middle once you cut the outside to size, buy a carrage bolt and washer from you local hardware store to match the size of the hole in the track and to match the guide ring on the old roller. Bolt it on "tight". You don't want it to turn like a roller, you want it to slide, like a snowmobile slide on a track. They worked very well for me, I always tried to run into some deeper snow to estiblish some ice on the wear bars.
