Anyone know much about gauge clusters?

I did the Autometer swap too, and I must have had better luck than you. Mine works and looks just great. I am quite pleased with it.

The odometer mileage is stored in a separate little circuit board which plugs into the larger instrument cluster circuit board. As long as you keep your original odometer circuit board, you will keep your original mileage. This is very easy to do, and I am confused as to why those over in the referenced thread on Corral.net couldn't do it.

The car's computer has no idea what the numbers are, on the speedometer face. All it knows, is that (for example), it needs to put the needle at the 50% point for 80 MPH. That is correct for a 150MPH speedometer face. If you have, instead, swapped in a 200MPH speedometer face, the 50% point might be for 105MPH. So, you are actually going 80MPH, but your new speedometer will be indicating 105MPH. Of course, as originally pointed out, one could possibly re-program the car's computer but that would be some very involved and presumably expense undertaking.

i bet that cost a bundle of money. Where did you buy yours?

I was Very happy with the way the Lunar Cluster looked. I tried two different ones and all the gauges were just a little off. It said I was Idling at 1100 rpms and was going 55 when I was really only going 50. It just got kinda frustrating. I'm glad your happy with yours. I got mine lowered with my autometer credit, but it's time to do something with the dash again.

I just compared the reading of my Autometer gauges to the digital odometer-test readout.

The speedometer gauge and the digital readout, and they differ by just 0.6 MPH.

The tachometer gauge and the digital readout are a bit worse, they differ by about 150 RPM. If I get ambitious someday, I might remove the bezel, and reposition the tach's needle by the 150 RPM to get it the same. However, 150 RPM is just one and a half "gradient lines" on the Tach, and in reality, I don't think I ever read it all that closely (the needle keeps moving to much! ).

I never did this same comparison with the original, factory stock, cluster. So, I have no idea if this is better, worse, or the same.
