    I am in the process of changing over to the gauge cluster with the stock tach and have a couple of questions. What type of plug to I need to plug into my distributer for the tach. And this new cluster has a mechanical oil pressure guage that has a metel line that has been cut. Where to I get this line and where does it go on my motor. Last but not least one of the ends in the flimsy copper panel is torn off so the gas gause won't work. Is there anyway to fix this? If not where do I get a new one. NAPA or do I have to go to GM? Thanks in advance for all the help.

    A .250 Female spade will plug into the distributor terminal marked "TACH". You can replace a piece of circuit board by carefully soldering a piece of wire onto the ends that are still there. With a razor blade, you can scrape the plastic coating off the copper trace and solder a wire there. Don't use too much heat or the plastic will melt.
    If the end is torn off where the plug goes you might make a wire jumper from the correct wire (brown I think) to the terminal on the gauge.

    Be careful of the gauge cluster itself. Friend melted a tach dash trying to put it into another year, without checking the wiring layout. What a waste.
