Drill a 1/4" deep hole in the center of each rivet with a 1/8" diameter drill bit. This is a pilot hole. With a 1/2" drill bit, drill into the pilot hole and "drill away the rivet heads". A cold chisel may be handy too, and a big hammer. You may need several 1/8" drill bits, they are easy to break. Do not drill past the control arm. Use the chisel at that point. Once the head is gone, punch out the rivets. Metal is best cut SLOWLY with drills... use a variable speed drill.
