I sure hope my car is an exception. I just sent my 69 convertible to paint with 69 HT door hulls on it. They already had the remote mirror holes existing from the original car they came off of. I just matched the passenger side holes to the driver side and sent them on their way. Maybe the factory plastic spacer on the remote mirror will tilt it out since they are wedge shaped. I thought the convertible vent post was a bit more "vertical", like the windshield is. Maybe the mirrors you have seen had rubber gaskets instead of the correct plastic spacers. I hope, I hope!
