If you have painted or treated the rear surface of the dash panel pressing, you may find that the gauges do not connect to ground satisfactorily.
When I rebuilt my dash, I ran a separate ground wire to all the gauges, daisy chain fashion, to a common ground point.
Connect the wire underneath one of the dash instrument clamp screws using a slip in "open" type terminal.
Relying on mechanical grounds is always suspect as things can change and cause you grief with intermittent faults.

After I powered coated my dash, I created this wire so that the sound was connected... without I had no gauge lights!
