Ted, I'm changing my idiot lights for real gauges. Part of the reason is my original dash did not include a tachometer and I would rather have an original-appearing in-dash tach than an aftermarket tach mounted in some awkward location. Regarding the other gauges, I want to KNOW my oil pressure and water temp, not just hope the red light comes on at a convenient time if and when something goes awry.
Regarding the printed circuit board, the one that came with my dash package (which I bought from a guy off this website) was very decayed and I had to buy a new one...and they're not cheap. The best price, I think, is offered by Muscle Factory out of Anaheim ($95). Their toll-free # is (800)762-0317.
Good luck.
