Are you talking about the holes on top of the lip for the hardtop. If so I would use some aluminium 1x1 square tubing and attach it through the hard top bold tubes, then mount the high lift and shovel on top of the tube. The tube would spread the weight and stop the tools from damaging the paint/denting the tub and having rust start. Steel flat stock would also be a possibility as you can weld the brackets to the flat stock and bold the flat stock down.
