Ammeter to Voltmeter...who does it?

I just did this swap on my Barracuda.

On the old ammeter face plate you need to grind off the rivet that holds on the plastic piece. Remove the two screws on the new voltmeter and test fit to the old face plate. You will have to drill two small holes on the old face plate. Measure twice cut once... haha. The previous pages you can see how much to grind off the old face plate. Hope that helps a little bit. Just keep test fitting to make sure the needle does not get snagged anywhere.
