What are the correct measurements for the bolt holes for the side lamps on a 1913 Roadster ( with the brass molding in place )?email@example.com
I assume you mean what are the locations for the holes for the side lamp brackets - not the side lamps since the correct lamps would have separate brackets. Late 1914 Lamps had the brackets riveted to the lamp and those have a different hole location. Not everything having to do with the dash is a 13/14 similarity.
Hmmmm . . . strictly speaking, the "bolt holes" should be 5/16". Now; did you want the distance between the two bolt holes?
