So I bought an old mounted ford disk. It has wooden bearings. Some of them will probably need to be replaced at some point. I found a company called Woodex that makes replacements for some models. Does anyone know where on the disk I should look for the model #?. It's been painted JD green, so if the # was in paint or a decal, it won't be there. It there a better source for bearings I should be looking at?
