Answer 1

The bracket is either held to the bumper cover with sheetmetal screws or white round inserts that have 4mm X 25 mm bolts 8mm heads then the licence plate is held to the bracket with 6mm X 15 mm bolts 10 mm heads into spring clip nuts. I saw a neat aftermarket bracket that screws into the tow hook hole. Stillen.com I think? that tow hook bracket allows mounting with out drilling holes in the bumper cover.

Answer 2

hard matter. lookup with google or bing. that might help!
