I have a plug in my fender because a previous owner drilled in the wrong place.
++ Drilled on the passenger side instead of the drivers side.
++ Drilled too close to the hood opening.
I installed an antenna into the hole; got it standing straight; looked good --- then I raised the hood. Rats! I put the plug back in.
Antenna template from Tim Lederman's site:

Template with rulerFred: Is Tim's .pdf of the template the actual size?
EDIT: Never mind. I printed it out and measured the hole. It is 13/16" diam ... the .pdf is full size.1951 Radio Service Manuals
