Hello, I have a 1951 Farmall super A I'm in the need of a steering wheel, What Dia. wheel did they use on this tractor, EBay offers a 15" and a 17-5/8" steering wheel both stating they fit the Farmall Super A.
Also what holds the steering wheel on? I'm guessing a big nut ?? If yes mine has been twisted off, What do I do about that ??
