My plate holder was not installed when I got my Yellow 05 Roadster, and I will not install it until I get a fix-it ticket. Here in Calif. it is considered a fix-it item, so what I plan on doing is to the attach the plate with double sided sticky tape. I tried it and it works good, no problem removing the tape later. I mounted the tape on the back side of the holder were the screws would normally go. I keep the holder, license, and an extra brass frame (goes with the yellow) in the trunk, without screws, saying "I need to buy some, but have not gotton aroung to it yet."
