Could somebody show me the shape of the head and the width of the base for me please? Our dealer used a special bolt/screw so they could fit their tacky plastic frames. So naturally they chucked the factory bolts that fit. The ones they provide only go in about halfway so the plate rattles and a hardware store trip is in the works for later today. Any help would be greatly appreciated.

 

Never mind. Got what we needed. Plate no longer rattles.
