Making a custom Turret board isn't that hard to do, although you do need some simple tools for installing the Turrets, last time I visited the Evatco website they had all the materials and tools in stock needed to make Turret boards, you could use the old board (it looks like a Fender-style eyelet board) as a guide, and then draw a layout on some paper, note that I have never in my whole life made a Turret board so I'm no expert, but I wouldn't mind learning how to make them myself.
