If you replace your cabin filter, there is a need to remove the windshield caps and screws to get at the cabin filter. These caps are easily lost. I just purchased a bag of four ($8.00) from the local Ford Dealership.
Thanks for the info. I've lost a couple of these caps and was wondering if the dealer could only sell them as part of an assembly. $8 for 4 screw caps seems like a lot, but I checked the online prices and shipping costs make the $8 look like a bargain. I'll take this part number to the local Ford dealer.
