Thanks guys. I should have mentioned that part of my goal is to keep the car looking as stock as possible. T-bolt style I could live with, but worm gear clamps scream cheap when I see them. I have one at the thermo housing and can't wait to get it off, I'm annoyed every time I look at it.
How bad could the OEM clamps be? Mine are 20 years old and still holding fine, but I know they're not going to survive removal.
