The front bumper Pontiac arrowhead emblem on my '68 Parisienne needs replacing. I was told reproductions are not available for full size. Well I found one for a '68 Firebird and it is identical except the studs are out by approximately 3/8" each (closer together). Has anyone ever made one of these work? Or is there another one same or closer to original? Here's pictures comparing to my wall hanger.
