70 Dart turn signal switch

Chrysler might be the only brand that had a little roller contact there. Certainly costs more to make. @slantsixdan
Several years ago, I had a used switch from a 68 column that I was going to ship to a member in UK. It tested good with ohms meter. Before boxing it I decided to clean it a little with compressed air. That little spring was rusted, went to pieces, gone with the wind.
