can someone please tell me the size of the bolt that holds up the panels in the wheel well. i'm missing the middle one and the loose panel hangs down and rubs against my tires when i'm driving.

 

I would suggest pulling one out, taking it to the dealer, and getting the correct screw.

They are not bolts. I will say that you could also pull one of the many located in the front inside fender and use it on the upper hole. The inside ones do not do as much.

If I recall correctly, they are 10mm. You should have around 6-10 of these screws in each well, so one missing screw shouldn't effect the panels.
