Yeah, he's talking about the ones on the old F-150s. They absolutely can crack your windshield. Nowadays it's just a set screw that can easily be removed with a torx bit.
Same for me. I'm a mobile window tinter, so I travel all over OP, Middleburg, Fleming Island, etc.
I wish someone would start a North Florida Maverick group on Facebook. I think we'd get a lot more activity. I'd do it, but I don't have the time for it.
