Hey Mark, both of my cars have them fastened with upholstery screws but I cannot say with certainty that they are original. I looked it up in the online parts book so graciously supplied by Jim B of Washington. On page 27 of section 30, under 30-10-14, group 30.602, it lists the kick pads as "Cowl Trim Panels" and list a qty of 14 "Screw with L/W" as the fasteners. KF Part number 203872. I don't know what the "L/W" means, I doubt that it means "Lock Washer" as in most cases those are called out seperately. Anyone else have any comments/input on what "L/W" refers to?
