I just got my registration in the mail today, and I started to remove the dealer tag on the back to install my permanent license plate. After I removed the dealer tag, I discovered that they had drilled the license plate holes in the wrong indentations to fit my plate. There are two other indentations at the correct spots for screws to go. The dealer had filled the first holes with some kind of putty to help keep the screws tight, I guess. I am going to drill the two new holes in the correct places for my plate, but I don't know what kind of putty or filler to put in the holes that I drill, or if that is needed at all. Has anyone drilled new holes for a rear plate, or how are your rear plates attached? Thanks for any info...
