Ok, so a '46 EL & FL should have the mount above the sidecar loop casting. It appears to me that the pipe clamp is a "C" shape, but not certain. From my research, approximately an equal amount of bikes highly restored & original condition have the clamps above & below the casting on 1947 EL & FL models.
As a Senior Judge, what's your take on this? I'm not having my bike judged, but I't seems to be a detail that varies in placement & type of clamp.
Once again, I appreciate all the help you give. -Bob
