OK. Since I have gone through all 9 yards on rally clocks, this info might be helpful. The rally clock is worth around $150-350 by itself with "knob" The knobs are somewhat like 280ZX with analog clock, but different. (If you put a smallest washer and mechine screw from jewelry store, it can be used) The lenses are often cracked and it can be rusty inside even though the dial looks Ok. The most important thing is the working oscillator. I fould out that tt can be repaired at one or 2 places in Japan. (It conists of many resister and it can be repaired if you are lucky for $250-600. You also have to send it in with the clock. (The clock itself has only a motor and gears, but no timing components.) Now before anything else, please know the following fact about the clock. It looks good and everthing, but it also makes a awful laud noise. (I have a NOS rally clock on mine, and still makes a big motor noise) And it also consumes battery energy while it is parked. So I have my car's battery disconnected while it is parked. (If it is parked for a week to 10 days, it could kill your battery) If you wish to have them repaired, I will be more than happy to get it fixed in Japan. By the way, the callender clock is a good alternative for those of you who want "Rally clock look" on your car. It is traded at farely reasonable price in Japan and they have less issues. Please note that there are 2 versions (early one and late one) buy either one can be fitted as long as you change the connector at the back.
