There are quite a few spot welds, they are best removed w/slow drill & spot weld cutter. Look like a small dimple in the metal near the ends/edges. Rockers need to be spot welded back on, easy job for a welder, really need a MIG. Drill or punch holes in new rocker in same # of places the old one was attached with, then simply fill holes w/weld. Keep clamped tight w/screws,Vise-grips whatever. I left mine bolted to frame & did one side at a time to prevent any movement while/as rockers are removed. Brian
