Thanks for the info zkx14, I'm guessing I can buy the studs and screw or weld them onto the roof? I think a vinyl top would look good on the car. It looks damn good on your dart Brian.
I never used one, but i would guess you need a special 'stud gun' to put them on. They could be screwed on. I would be concerned about leaks,". My headliner is messed up from the original screw on the passenger side of that trim leaking.
