I just joined the st community with my 2017 Focus st and this vehicle didn't come with the engine splash shield nor the one forward of it that goes below the radiator. It also lacks the hardware to secure them on. The dealership wants almost $7 a piece for the t30 screws.... To my understanding the screws have a built in washer as well. Could anyone give me the dimensions of the screws or even part number so I can go to my local bolt shop and pick some up? Also how many are on each splash shield?
