You need to have the lower tip of the coil cover one drain hole in the A frame, but not 2, and make sure the flat end of the coil faces up, or the truck can lean. (The a frame has 2 holes in the pocket that the lower tip of the coil mounts in for drainage, the tip should cover just one hole.) To tell which end of the coil goes up, set it on the ground like it sets in the truck, then end for end it, and look again, the end that makes it set up straightest faces up. Also be sure to reinstall the rubber cups (tape on) or you will get a squeak.
