I think there are at least three screws on the circuit board that are used to ground circuits on the board. Clean those and put star washers on them to improve your grounds on the board.

And on the rally panel there's a ground contact on casting for the fuel gage/IVR.

IIRC the screws that mount the bottom of the instrument panel assembly to the dash provide an additional metal to metal ground path.
