The code on my door for the interior is "EK" but I cant figure out what that is. I have a 97 Lariat supercab. The interior is med. prarie tan and mocha, I think, but I am not sure. I bought some floor mats from the dealer to replace my original ones that were trashed, and they arent the same color as the originals. the new ones are too light. I've had them for a while and it always bugged me, plus they wont stay in place. Anyone have any expertise in this area?
