Drill Holes In Framerails

Six 3/16-inch pilot holes were drilled through both sides of the framerails. Shortly afterwards, the holes were enlarged on the inside of the frame to 1/2 inch. The pilot holes on the outside of the frame were then hole-sawed out to 1 inch to accommodate six billet frame spacers. The spacers, once welded in place, serve as sleeves for six through-bolts that secure the new bellypan's outer brackets to the framerails.
