I have them also and can not use bec. stupid vent windows. I'm pissed at this side vindows you have no idea. Next time I paint my car I will get 2 complete 68 doors and change the them 67 doors.

I went and bought those too knowing that it would block the vent window on my car. Fact is they will never need to be opened, and if I find that it's a problem, I will put something else there.

I can’t open my vent windows either not only do the mirrors block them but they hit the 4th gen dash also.

Are the Buick mirrors smaller than the C5 mirrors? They look similar. I have debated on what mirrors to run for a long time and I have C5's for it now. Since I am as low as a Corvette, I want plenty of mirror to see what idiots are around me. Function (safety) is over ruling form on this issue for me.

Understandable. Some guy will be looking at your car then hit it by accident because they were looking at it closely. Seen it before.
