I have a 64 impala I'm restoring. It has the holes on the fender for the mirror. Does anyone know if this was a ss option or what? Ive been trying to research this and getting no where! I can't really even find a picture on line showing a 64 with those mirrors. I do plan on keeping them on the fender. Kinda gives it a cadillac look. JFK/GANGSTER LOOK?! Someone mentioned it could be dealer installed? Probably so since I've learned lately the mirrors are actually 60s sears outside chrome mirrors! And mine are closer to windshield. Not in center of wheel. Guessing these mirrors are rare? Ive since found 2 more on ebay. But cost was twice the "original" bow tie. Any info or input would be appreciated!
