Gauges - Marine - restorers - Chris Craft and other:
I can say that Mark clawson does top notch restoration on gauges
He was also very willing to update to modern electric movements in my tachs which is more accurate recording hours and rpms than the old tach drives .
He also upgraded my amp gauges to volts and I had him add fuel gauges by turning the orig. temp gauge into a dual gauge as to not drill extra holes in my helm.
Heres my gauges all ready for when my helm itself is completely restored
