Brief Description: Attached the main 12volt distribution board
5mm holes where pre-marked and drilled for the screws in the firewall but the blind nuts on the firewall side stuck out too far, so I drilled the outside firewall hole (the firewall is two layers of carbon fiber separated by about a 1/4 inch of foam) to 6mm so the nut part of the blind nut would penetrate so that the sharp progs would penetrate the firewall heat shield and stop at the outer firewall (with the treaded nut portion stopping before it gets to the inner firewall). This worked well and the blind nuts look corrrect. Mounted the main 12 volt distribution board that I previously attached the Rotax AMP connector and 912iS key box to.
