Ammeter to Voltmeter...who does it?

I'm beginning to wonder if the photos on the previous pages are not loading? Basically all you do is remove the ammeter scale / face and mount it to the voltmeter. You can use the voltmeter face as a template for the two new holes. The little cal pot in the voltmeter is used to adjust voltage to desired "point." Unlike others on here, I set 14V to be right at center, the old "O" point on the ammeter scale.
