Hi,
I just recently purchased a 2004 Crossfire coupe with 33K miles. It is a very well taken care of car. While going through the car I found 4 rubber plugs laying under the trunk floor near the jack. The part number on the plugs is 124 997 07 86. This appears to be a Mercedes Benz part number and Mercedes has it listed as a "Stop Plug" and also as "Plug, Side Member Front". I have looked under the car and I don't see where these 4 plugs would go. I have attached photos from a Mercedes website of the plug. I would appreciate any help you can give. Thanks.

 

 

No luck finding this out for you. I found on a Mercedes owner site posting where the member said he found these on the floor by his brake pedal after having the dealer replace a water pump. A parts website referenced the part being associated with the Front Left Wheelhouse. Without taking the wheel off I used a mirror and flashlight to look around and behind the front wheel on my convertible and didn't see it, but my view was limited. I also did a search for "plug" in the 2004 Crossfire parts manual and found a plugs chart on page 227. The Chrysler part number is: 05099362AA. There is no parts diagram reference where this goes. This certainly appears to be a body sheet metal or frame plug.

 

They are exactly what onehundred80 said they are. I found 4 of them in a sealed plastic bag in the glove box of my SRT6. I guess who ever prepped the car at the Chrysler dealer, didn't know what they were for or just too lazy to put them in the holes, so I did .

 

 

Thanks everyone for the input. Since people have found them inside the car the plugs must be for the tiedowns during shipping. I'll examine my coupe again and see if I can find 4 elongated holes.
