I contacted classicinstruments about having them retrofit the panel of my Mach 1 with their G/Stock gauges. Speedo, tach, and dual fuel/oil, temp/volt. The quote was $2000 with an 8 week turn around time. The gauges can be individually purchased from summit or egauges.com for $543 with senders. That means they are charging $1500 to install it to YOUR panel. At least JME gives you a new panel.
