I have a customer looking for an antenna hole plug in the windshield center dowel for a 1939 Convertible. This is different than the closed car that Carpenter makes. Ford show part# 91A-7403456 for 1939 and 1940. I have never seen one.
Regardless, I made a 3D printed (pla plastic) version of what I thought the plug might look like. If anyone has one, or seen one, did I get it close? Also what color should it be?
