Rock Tamers® Bolt Hole Punch is used to punch the top row of pre-molded holes into the mudflap (item RT022).
After holes are created using this bolt hole punch, assemble the cut end of mudflap into the flap clamp (item RT048). Complete the process by re-installing the flap clamp bolts (item RT056).
