anyone know how I can do this? I replaced the illumination lamps with wedge-base LED's from ledlights.com, rigged the cluster back up, and nothing. a little reading and I realized that they are polarity sensitive. Before I pull the thing back out I was wondering if there is any way I can verify I have them installed the right way before I put the cluster back in? Of course it could all be that stupid rheostat -- I tried to jumper it but I couldn't get the solder to stick?

Minor successes:

Replace the clock capacitors, clock works now!
Re-stuck the metal buttons that had fallen off two of the instruments

Minor failures:

Repainted needles. They came out really poorly. I'm going to have to try it again at some point, but I'm not looking forward to it.

I'm not up to snuff on your light bulbs but I do know about your solder. You have to use an acid based solder, resin based won't stick.
