My 78 F-150 Lariat is a soild color ,it is listed as as a Tu tone delete on the window sticker. In addition to the race track trim it also has the lower trim along the bottom of the truck even across the tool box and the wheel well trim. I have read from a 79 Dealer book that you couldn't get the lower trim and wheel well trim with the Lariat option. I have seen a couple Lariats on ebay with this also. I sure looks factory to me. It's not listed on the window sticker though. I am waiting for my Marti report to come back and see what they say. Maybe the dealer installed it ,I don't know .
