Not shure if it is possible(just the clock). LCD display is a pretty touchy thing. Need to take cluster apart to look at the circuit board to tell for shure. Even if you can feed the power to the clock display, then you have to isolate it from the rest of components it shares power or ground with. There are lots of in-dash gauges(clocks) that look good: Auto-Meter and what not. And clocks are the cheapest of all instuments of all, prolly.
