I have found some sheets of Perforated Metal as it comes in many sizes as I am trying to duplicate the look on my 1971 DT1 MX

Thank you for any help on this.

Greg, I have two DT1 MXs. The holes are 3/16 diameter and they are 1/8th inch apart. I hope that makes sense. Let me know if I can measure them a better/different way.
