They didn't Steve, it's an aftermarket.

I bought and installed one of the quartz replacement movements on my friends 67 vette as a birthday present a couple of years ago. It keeps great time, even through the Michigan winter. Before I installed it. I thought it would have that jerky hand movement that all modern quartz wall clocks have, but not so. The hands move smoothly, exactly like the original clock. The replacement itself was not too tough, and clear instructions were provided. I also used one on my tic-tac-clock, although it isn't in the car yet. I personally think a working oem analog clock is a cool option. If a non working clock can be found at a decent price, a quartz movement and a reface decal gives you a brand new looking and operating clock.

With a reface decal and new quartz movement can you make a clock from a delete plate?

Nice thought, but not possible. The inner workings of the clock, as well as the hands and adjustment stem and knob, are all reused. After rebuilding mine I saw that the original "winding" mechanism consists of a solenoid that turns a wheel with a spring around it about 90' each time it fires. This allows the clock to run a couple of minutes. As the spring unwinds, 2 points (think of miniature ignition points) touch, which completes the circuit to the solenoid and fires it. These points wear out, and then don't complete the circuit to fire the solenoid, and the clock stops running. The rebuild kit only replaces that winding part of the clock. There is only one wire that goes to the clock. That is the positive supply, while the negative goes through the metal case of the clock. The light is the push in type, not the twist type of the dash lights (no printed circuit board to supply power). I tried filing the points, it ran for awhile and stopped. All of these observations and comments refer to 1968 -69 -70 dashes. Earlier cars may be different.

I'm with mike69r/t - I installed one of the quartz replacement kits in my '66 back in February & it hasn't skipped a beat. Not only that, but it keeps perfect time and runs very smoothly, unlike the original mechanical clock. Interesting observation about the Corvette connection - GM,Ford & Chrysler all used these "Borg" clocks back then. In fact, the instructional DVD that came with my kit showed the procedure on a Corvette clock - exactly the same movement once the face & needles are removed.
