Does the O.S. .46FX have the same Back PLate Mounting dimesions as the O.S. .40 FX ???

There are a lot of backplates available for the .40, but not sure if they will fit on the .46.

Thanks,

daven,

The cover plate for both the O.S. Max .40 FX and the .46 FX is the same part.

Does the O.S. 56 back plate fit the 65? I'm building an engine and need a backplate

Thanks

Ken
