so did you just have to jack up the rear end causing the pack to push against the underside of the bed and the top shackle bolt came out? I leaned on mine pretty hard and it still hit the rivet? weird
Yes. I didn't have to go any further than just having it sit against the bed. My spring clamps on the front of the springs were on when i did it and still are. Don't know if that helped or not. Mine didn't hit the rivet.
