Drill-less accesory mount for mk7.5 golf/sportwagen

I needed some accessory lights due to location, but didn't want to drill any holes or anything through the car itself, so i made some mount that fit the ID of the lower grill cutouts. These do fit through the upper grill holes, but not through the lower ones for installation from the back. Shape does not allow the mount to fall forward out of the car, so far doesn't appear to easily get pushed back into the car.
