Quoted from Westbury:Does anyone know where to get upper playfield flipper rebuild kits, im pretty sure they are not the same as the lower ones, i seem to be having trouble finding where to get them, Thanks in Advance!
not sure if you got your answer but i ordered for a friend on action pinball. Installed and worked great on the upper flipper.

Although, it didnt come with the spring washer but the use of those is debatable. Flipper works great.
