that is a good idea, may have to do the same as my rear tag is mounted in the center of the truck,, have not received mine yet,,,,, guess it takes awhile to cross Tx

do you have one big magnet or two?
so I suspose you prefer the back rather then the front lic plate, I could mount mine on the front but I will to wait and see,, is your real glass dark, mine is pretty dark so it may be hard to see from the rear,,, you do have a good idea though,, regards..Fred
