What year and model? I've reconditioned a few early 40 speedo-odo assemblies. Mostly takes time and a LOT of patience. Then again I am biased: my grandfather was a fine jeweler and watch repairman, so it's genetic!;p
The "newest" pig - 78 w/ cali emissions' odometer is stuck at 59600. I've got a few names from Hemmings but thought that I would check w/ the board first. And I know, this is worthless with out pics - I'm working on it.
