2 questions where's a good place to gat a tilt coulmun without taking a second mortgage. and second car is about 90% complete but dash needs attention. I had to run a seperate ground wire to get the temp gauge to work. the amp gauge and dash lights are still MIA. the mylar circuit run behind the gauges look every bit of it's 50 years old. How hard is it to swap out? anyone done this before? While I'm thinking of it would it be smart to replace the amp gauge with a volt gauge?
