Hole Sizing – Switches & other components

Building, Repairing, Upgrading? The hole your switch or light mounts in is critical. Before you grab that drill, or order parts, here’s some sizing information to help get the correct fit.

  • The hole in the dash must take into consideration the dash covering and whether you wrap that cover into the hole or cut it out to the same diameter. 
  • The ‘finished’ diameter of the switch or component is given below. Your finished hole must accept this diameter
  • The ‘bezel’ diameter is the outside diameter of the component, at the point it bears on the dash. If you are replacing a part with a different style switch, you’ll need to know this to make sure the new part doesn’t ‘pull through’ the existing hole when you assemble it.
