Early GMC trucks changed their hood side emblems about as much as Chevrolet, however there is no similarity in appearance. The following shows the GMC changes over 14 years.
1935-36 Anodized silver aluminum with a semi-flat black background. (In 1936, GMC entered the light truck market and carried the emblem from larger trucks of earlier year) Right and left are the same.
1937 One year only! Made just like the 1935-36 except for the short wing extensions on each end.

1938-46 A more streamline design was carried through 1946. Its streamlined rounded point on only the front creates a different part for the right and left.
