Rewiring my EFI Magnum - 1970 Dart Swinger

Trying to figure out where to drill the holes for the screws that held on the old voltmeter face and will hold on my ammeter face. Notice I had to grind a bit on the centre of the gauge cluster so the little counterweight at the bottom of the needle will clear. Also needed some more clearance on the ammeter face. And I'll have to do something about the colour on that pointer. It doesn't look too far off in the pics, but in person it's way more red than my factory pointers.
