Ammeter to voltmeter conversion

Yes, that's where it goes, I had gotten the Sunpro stated above because others have suggested it, but it is way to small for that spot. Mine has a blank in that hole that's why I want to use it so I don't have to do any major modifications elsewhere.
Get a performance indicator (vacuum gauge) to put in that hole if you don't like the blank. Pretty in-expensive (1st choice a tach) and looks good in that spot. IMO a giant voltmeter would look terrible. Shoot me a PM if you are interested. I have a spare.
