1966 Dart cigarette lighter.

You lost me. Can you post a picture of what you have?
I don't have a photo now but let me see if I can explain what I'm looking for better.

The lighter consists of three parts. The knob (the parts that glows hot), the socket and the housing that goes behind the dash. I need the socket which is the part that makes the connection to provide power to the knob (element). This socket inserts into the housing, and is secured by a threaded post and nut. A single connector plugs into the post. It's the part that make contact to the knob (element) that makes the element glow red hot. I hope that explains it better.
