License Plate Light Placement

Here's a Bump for you. I Don't own a Duster, I have a 73 Dart but if you think a picture of that will help, I'll get you one.

Hey FABO folks,

Need to mount a license plate lamp on my 72 Duster, but do not see any mounting points (holes) for the socket. The wire and plug for the socket come through from the trunk via a single hole & groumet. But no obvious mounting point are visible? Can anyone post up a picture of an installed lamp?

Thanks in advance.

Pat
