I know the Parts Book shows that the Louver Rivits and the Door Rivits are the same number 6026292. I have an original louver car with painted racing mirrors and the Rivits are different from each other on the car.The Louver Rivits are longer. The Parts book shows two different Screws 3400353 for the Louvers and 187709 for the Door Mirrors.My Louver screws are much longer than my Door Mirror screws.

The Rivits in the picture do look much the same as the ones on my car, minus the puddy or body work that make them look tear drop like in the picture.
