I made a pattern in AutoCAD and used it to lay the cluster out on 1/8" aluminum. I changed all the lamps out for LEDs and added LEDs for turn signals and bright indicator. I built it about 10 years ago, a few years before the stroke and before LEDs became so common. I cut up an old dash harness (from my 73/318, 4 dr. donor car, K-Frame, etc.) to get the connectors, so mine plugs in like the original. The map lights and fresh air vents are Aircraft equipment and the fuse box is Marine, the relays are automotive.
