I have a 72 with the surging accelerator problem. I got a new bellcrank and throttle rod so I could perform this modification. I'm not a welder and was wondering how anyone else has done this mod without welding? It looks like I can use my Dremel and saw the arm off the weld but I'm not sure how I would attach a washer to the bellcrank. Attaching the arm to the washer I can see, but I don't see what I would screw to with the washer. Any ideas?
