That looks hot.
I never understood the security screw idea on the grills on these cars. If someone wants your pony, they aren't gonna sit down with a screwdriver and unscrew it. They are gonna grab onto it and RIP it off. I see Mustangs all the time with ripped off ponys, with the pony mount still in place.
I'd rather leave regular screws and have the person unscrew it rather than rip it off. Those holes that the screws thread into strip out rather easily. One good yank and it will pull right out and then you won't be able to screw anything in without repairing it
BTW, nighthawk, when i did my Mach 1 grill, there were no screws on that interior grill peice. There were the two holes, but nothing was in them. Did you buy your car used? Maybe someone already had a delete on it???
