also, u can go to an car stereo shop and ask for a peice of scrap carpet they use for building subwoofer box, have a piece thats big enough to cover up the back side of the licnese plate, then spray glue,and glue the carpet to it, use thin carpet , i did this and it works great, stops rattles from my 2 12's, before putting the plate back on, ask them if they have some foam tape, all u need is 1-2inches by 3-5 inches, next u stick that on the carpet, center it so its middle from left to right, but stick it at about 1 1/2 inch from the bottom of the plate, next screw the plate back one and u wont notice it . it might leave u a gap about 1/8inch maybe but no more than 1/4 inchs, hope this helps u out in protecting your paint. i have this done by myself since i owned the truck, 2.5 years and its still intact, no mold or water damage.
