Well this is my first time and it is a simple project. I simply wanted to take the license plate away from the car and lessen the sounds caused by vibration, the black car (Monte Carlo SS) has aftermarket stereo setup which causes a rattle I dislike.
Step 1: What do we need?
I decided I wanted a hard plastic clear cover which was like $3.96 from Wal-mart.
I then snagged some thin foam which can be gotten at www.nicolecrafts.com for basically 50 cents.
Used a utility knife and exacto knife, the kitchen cutting board, some scissors, a sharpie, and a screwdriver.
The good thing about this foam is when done you will end up with some scrap that works great for lining Altoids tins or other projects like that.
Step 2: Cutting
Once you pop open the plastic wrap for your cover the cardboard becomes our template, just sit it on the foam and cut around it, if you find it easier use a marker to trace it first. Once done cut it out in whatever manner you wish.
(You might notice the color changed, because I forgot to snap a pic with the full size piece of blue.)
Step 3: Mounting holes
Time to trace the holes, simply place the plastic cover over the foam and trace the holes, then remove them with your blade.
Step 4: Completion
Well that's about it, just do a test fit to be sure you have made the mounting holes large enough, then pop it back on the car. On one of my cars with 4 mounts you can't tell it is there and can only barely make out the blue on the one with only two mounting holes but only if right up on it and if you know to look for it. You can see the reason I replaced the previous plastic which was thin and cracking. Hope this is useful to someone, next thing I am planning will likely be a custom grill and a custom CAI (Cold Air Intake) for the silver car, the black one is already somewhat modified.
