1835c Drive motor rebuild

Hey all. So I have the right side drive motor not functioning as it should and I think i'm going to go ahead and rebuild it. The problem is the parts house I found the seal kits at don't know which kit it is, with or without the Teflon seals. One kit has to many seals and the other wont have enough. My serial# on the machine is JAF0012382. The parts house I found is LPS (Loader Parts Source). Anybody have any clues as to which one I need?
