I have two quick questions:
1.) What specifications do the capacitors and resistors have (or RadioShack cat #).

Again, thanks a lot for your help!!!!

The capacitors on the 300SDL's cluster were
220uF/6V
47uF/16V I think.

I replaced them with:
220uF/6.6V
47uF/50V

The resistor was 33 Ohm, which is available at radioshack as that's where I got it. The capacitors are fairly common values so I think RS should have them as well.

Just be sure to open up your speedometer first before buying supplies so you are sure of what you need. The first gen speedometers are different than the second gen. Second gen are what is listed above. First gen I cant recall at the moment.

I've not seen the replacing the resistor comment. I'd have to look at the clock closer and see. As long as you are using the same capacitance on the replacement capacitor I cant see an obvious explanation for the erratic behavior.
