Hi All, I have a question on the frame. What does this mount do? It is under the front of the cab with about 1/8" space between the top and the cab. It also has one hole in it. One picture is the mount(they are on both sides). One is me pointing to where it is located and the other shows that it is just in front of the front running board bracket. I have no rubber pad or anything that goes on it? Any idea? thanks, Nils
