Concerning the gauges, it kinda depends on your end goal. If you want original gauges the look new, I'd call Kocian, they are in MN. They rebuild yours. Now if OEM is not a concern, then I'd go new faria, Autometer, or SW. Others do exist, depends on preference. Aftermarket has lots of options, you can have several indications in one gauge, then add things like depth indicator in unused holes.
