The mirror should be mounted farther forward . Should be viewed through the vent window. This may be your adjustment issue. Plus, they are noisy when located back like that. My '69 Darts mirror, drivers side is viewed through the vent, and it is quiet when driving. I installed a passenger side the same, viewed through the vent. My '72 Darts driver mirror, is behind the wing vent, somewhat difficult to see and is very noisy when driving. Both driver's are in the factory location, so they moved them around. I am going to relocate the '72's mirror at some time. I like the passenger side mirror for lane checks and backing up on curved driveways. Relocation, fill holes, repaint that top portion of the door. Shouldn't even show up when done properly.
