I thought the speedometer cable was bad.
It turned out to be that the speedometer mechanism was frozen.
There is actually more miles than this.
My Dad drove it for (?) years with a broken speedometer cable.
Wiring needs attention. Broken and exposed conductors. Stock wire
length too short for easy cluster removal. Also an electronic flasher was
installed. Future LED stop / tail / turn signal lights are a greatly needed upgrade.
Wiring length extended and wire-tied into a manageable loom for ease of
servicing. All new lamps. All connections crimped, soldered and heat shrunk.
I did not use LEDs in the cluster. I want that nostalgic look
that I remember when I was 8 years old.
