Our plan is for a zero-rattle installation. Remember the shield is not a perfect rectangle so it'll fall into place one direction, or require serious bending to get it to fit in the other direction. If you can't get yours to fit, try turning it around. If it still won't fit, well, you suck worse than us. Quite a tidy installation.
Life is so much better now.
Instead of a pair of ugly ash trays that will never get used, we have six cool change cans ready for any coinage emergency. Our pockets are light, our spirits free, our tolls paid. Passengers marvel at our craftiness. I'm a guy. My purse is parked out front.
