You really don't have to rub it into my face with those fancy new minitub flanges
Just kidding, I wanted to do that as well, but just didn't want to take the time to accomplish it. They look great!
Any chance your car is a factory a/c car? Mine isn't and I am installing the Vintage Air kit. I don't like the VA dash vents, so I want to go with the original style vent. They have an odd shaped hole and I'm having a difficult time marking out my dash to cut that hole.
