I had access to a machine shop at one of my past jobs and just made the end different rather than the end that it came with. It worked fine as it was I just made it a little better... another word of caution !!! .. if you mount the stop to the rear carb bolt it can pivot and move back slightly no matter how hard you tighten the bolt / nut . I remedied the problem by drilling another hole in my Jegs linkage bracket and added another bolt to hold the stop from moving now it can't pivot or move
