It looks as though the GMC style ornament I have is a little longer than 12" center to center.
I picked it up from another Stovebolter and assume that it is an original GMC unit. It doesn't appear to have been damaged over the years, yet the holes seem to be further apart than expected. (The GMC style unit I have is a sheet metal item. Does anyone know if the original GMC ornament was sheet metal or was it a cast item like the Chevrolet?)
Perhaps a 1940 GMC owner will notice this thread and let us know what the measurement on their hood ornament is.
Thanks
