I was thinking about ordering a gear box and maybe some rebuild kits for the left and right side gear box's for my Walker. I read in the J. Thomas catalog that they manufacture their parts. How are they compared to OEM stuff ? Price / Quality ? My nearest dealer is about 20 miles away and he just about always has to order my parts. I pay for shipping. I'd rather order direct and have it shipped to me if I'm going to have to pay shipping.
