Im looking for a propeller spinner and back plate for my 14-13-2, it has the 0-435 engine with a Hartzell prop. The old spinner is 13 inches around and has a internal cone with a hole in the center that fit over the round nut on the front of the prop. The back plate fits on the back of the propeller with 4 metal flange that attach to the alum back plate and screw into the back of the propeller. would anyone know where I can find one? or what make of aircraft it's came from?
