• Remove the brackets and tie a string between the clamp holes to get the center line and keep the clamped angle the same.
• Tape the area to be drilled to help keep from chipping the outside edges while drilling.
• This one was drilled 1-1/4“ up in a drill press.
• Be sure to leave enough meat between the hole O.D. and the edge for strength.
• Use the same process and measurements on both sides first.
  • You may find that the factory holes are not quite in the same place on both brackets.
  • You may also find that your exact (matched) measurements would end with the new hole being closer to the edge than the other bracket. So, you'll have to improvise a little.
  • If the new holes aren't perfectly drilled to match on both sides, it'll still work.
  • It will probably be barely noticeable if at all.

• Use a punch to set the center of the hole for the bit.
• Pre-drill the hole with a smaller bits in steps up to the final drill size.
  • This will help keep from burning the bits up while drilling thru the stainless steel bracket.
  • Heat will build quickly so use plenty of cutting oil to keep the bits cooler.
  • If it starts smoking, stop and go back to a smaller bit and then step back up to the final one.
