    Gas/Temp Gauge Ground Nut Missing

    As the title states I am missing the ground nut that goes on the back of the temp gauge and the gas gauge on the back of the instrument cluster. I pulled the cluster because the temp and gas gauge were jumping all over the place.

    Anyway does anyone know what size nut goes on the ground? I figure I can run to Home Depot and get it if I know the size...

    Thanks.

      just bust into ace hardware with your cluster and test them out. i think they are the same as the ones on the taillights as far as thread pitch but the tail ones have a built in washer.

      also go to ace, not home depot. ace's metric selection is infinitely easier to sort through and they have a way better selection

        RealOEM.com might list the size.

              Just for documentation, I had a missing ground nut on my temp gauge and replaced it this weekend with an M4x0.7 hex nut. 7mm is the socket size for the nut.
