This is the best pic I have of my drivers mount. This one is a steel mount as I run this on the drivers side and the rubber one on the pass side. It has one stud on the top that goes into the eng bracket and the 2 on the bottom go into the frame. Its kinda square as its about 1-1/2 to 2 inches thick and then about 3" x 4" in size. Hope this helps some. Ron
