Dashboard fun

 
Well, with the engine running, now I can turn to more mundane aspects of this car. Here you see the speedometer and tach cluster. What you can't see is the back of the tach, which I forgot to photograph before I put it back together.

The tach is a GM model from a Grand Prix, but in an amazing stroke of foresight, GM put jumpers on it so that it can be used on 4, 6 or 8 cylinder engines. In its rush to save money, it made that selection jumper very, very cheap. It rattled around, and when it lost contact, the tach would switch to 6 cylinder mode, and read 1/3 higher than it should. It was annoying. I soldered a wire to the contacts. Shouldn't have that problem any more. I also washed the clear face while I had it apart.

See this is the kind of detail you just don't get watching a show like 'Overhaulin.'
