68 Barracuda Alternator upgrade.

I did mine, left ammeter scale, adjusted the pot for needle to read slightly above half line at 13.5V i clipped and super glued the stock ammeter needle in place of volt gage needle to keep stock ammeter look. Added a tiny red discharge light to the left of the D on the ammeter face. Used a #50 drill for a tiny hole, jb welded a 12V red led from behind so its not visible until it lights. wired it to my L terminal on the denso.
