I need a couple of parts & some help, please.

1) I just took a rock to my passenger / right side foglight, anybody have one?

2) My car has been missing the access door to the drivers / left side foglight since I bought it. Again, anybody have one?

3) Any advice on removing and replacing the passenger / right side foglight assembly?

4) Does anybody have the M-B part number for the 2004 engine accessory drive belt tensioner? The idler pulley is on the cross reference list, but not the tensioner. Also, has anybody had a good experience with any aftermarket (Gates / Goodyear etc..) replacement belt tensioners? I do not want to install something with the wrong tension and ruin bearings in any accessories.

Thanks
