I have a backplate for a 40-46SF part#25407000
I am not sure if it will fit your engine or not though.
Maybe someone can chime in
Just checked, I got one. Send me a couple bucks for shipping and it's yours. PM me your address and I'll get it out tomorrow. I'm going out of town Friday so get me your address qjickly.
