03' Jeep Grand Cherokee. I'm replacing the sway bar on my front end, and the welded nuts inside the frame for the bushing bolts snapped from the frame, so now the bolts are just spinning. Am I better off just grinding the heads off the bolts, pushing them into the frame, and then using self-tapping bolts to reinstall the new sway bar? There are no access holes on the frame, and I would rather not go cutting into the frame.
