The MSD will hit the rubber and some of the fiberglass part of the AGrabr. The Mallory will also fit along with the Mopar one. You can also recurve the Mallory easy enough, and they sell springs for it as well. I have since went to the Mopar one when I found someone that does a great job of recurving them. It just looks better without that big red cap that the MSD has. The Mallory one I painted tan.
