I love my s5 more than I love salt water taffy, and I love me some good salt water taffy let me tell ya. My fat friend ripped the buckle out of its track in the passenger door. After I pulled my knife out of his stomach I inspected the damage in the door. The track is bent and it doesn't look like I can simply stick the buckle back up in there so I'm faced with a dilema and a few questions....

I need a new track. I called many a junk yard in my area but no dice. Looked around online but couldn't find anything. Is the part cheap and does anyone know a good place online that sells parts like this?

Also, can anyone tell me the easiest way to tear apart my door without scarring it up? I don't want to pay anyone to do the work for me and there is absolutely nothing else wrong with the car and i'd like to keep it that way....

My girlfriend wont even ride in my car because she doesn't want to get cut in half by the lap belt if there's an accident......any help is appreciated.
