Hello from Oregon

I recently purchased a 1972 Dodge Dart Swinger and have been using it as a daily driver. This is my first early model dodge and am finding out that it is a different beast from my fords. It has been a one owner car with a stack of invoices and the original purchase sheet.

I just installed a dual exhaust system with X-pipe and a new heater core. I also just picked up a 71' Dart grille to be installed. It has been the best car I have ever picked up and drove. I do have questions and figured I should get with some folks who know. I will post pictures here soon.

My first question is that there is a hole in my dash about knee level under the headlight switch. I have looked through a few other cars and it would appear to be a MAP light switch does anyone know where I can get one of these switches?

Thanks Jason
