Ok, please let me know if you find one. Is the flap supposed to be on the outside? I put my hand up there yesterday and couldn't feel a flap. If it's a WA rig, I'm sure it's in better shape than one from here with the heat we get. I found it for $32 on a dealer site so I may just do that. I'm going to pull the inner panel and see if there is a flap there. I'm getting a huge amount of fine dirt and silt from the roads around here. Makes it hard to breath.
