Have been working on the ole vette this winter and am just wonder exactly how the kickpanel screws attached around the air vent on the passenger side. Mine seem to just have funky holes dug into the black plastic vent cover with no real holes into the side panel of the car. Is that correct? Sure doesn't look like it to me. I have an AC car, I don't think that matters although the passenger side vent door cable is re-routed the the dash knob.
