I recently neglected to put in a couple of screws on the front undercarriage cown on my 300D. Well, the wind got a hold of it and ripped it completely off. I want to replace it to keep the elements (snow/ice) from gaining easy access to the front underbelly of my car. Anyone know where I can find this piece. It looks like it is made of fibreglass. I went to several local junk yards but, no luck. I also need tan AC/Heat vents (left and right) for the driver side and passenger side. The car is from Florida and the Florida sun made the vents brittle and I broke them. Any advice on where to look for MB parts like these would be greatly appreciated.
