Speedo issue

['68OrangeSunshine]

Lubing the cable is easy, and if it doesn't work, then you know you need to go deeper.
Disconnect the speedo cable from the back of the dash. You also disconnect the connector at the transmission.
[I had my dash off, so it was even easier].
Get a tube of graphite lube dust.
Pull the cable all the way out and work the dust into the cable by pulling it thru some dust in your palm, until you get back to the end.
Attach the tranny end. Twist the cab end a little to feel that it's seated, then plug it back into the Speedo. That took a lot of the swing out of my Speedo needle.
