When I finally got the '48 out of its rebirth, the speedometer didn't work right, and after a bit - quit working at all. I pulled the cable out of the housing and just put getting the speedometer right as the last oh-by-the-way project that I would finish up.

Over the winter I sent the speedometer back for a checkout and the verdict was that it was OK. Barring an issue with the drive gear in the transmission, that leaves the cable as the biggest suspect.

You cut most auto store cables to length. Since things didn't work the first or second time - just how much cable should stick out of the housing to engage the drive socket on the speedometer? Any hints on getting it right the third time?
