The truck is a 2010 F250 king ranch. It’s a crew cab four-wheel-drive, with 6 1/2 inch wide runningboards. I’m trying to locate the passenger rear running board in cap. Only part number on the cap is 9C3J-16450-AIP7…which crosses to nothing and I believe is a general part number for the whole running board assembly. I’ve messaged a couple online oem parts stores to no avail. Any help is greatly appreciated!
