Ammeter to Voltmeter...who does it?

I tell you what i will also be modifying on the back of the cluster housing. The ground points to the circuit boards. I intend to drill out all the board mounting screw holes in the metal gage housing frame, tap the holes for 10/32 threaded screws, and superglue threaded studs in the tapped holes. I had 2 of the self tapped screws that were stripped in the housing, if i have to modify these for studs, then i may as well modify the remainder. My other option will be to helicoil all the grounding screw holes to a 10/32,:and use some nice stainless steel phillips button head screws.
