Welcome to the Z from Calgary! Glad to have you on the board as a member; Tell us more about you and your truck; got any mods done to the ram, and what kind of mods are you looking to do to the truck in the future? Performance/appearance/suspension? Lots of options, and hope we can answer any questions you might have.
Sorry I can't be of much help, but drilling out the existing bolt would probably be your best chance, don't know how much room you'll have to cut it out.
