I have 70 340 Dart Swinger with A/C doing the exact same thing. I have replaced the ignition and turn signal switch. My column gets so hot you can dang near fry an egg on it. I also have Hedman headers and the engine bay seems to have more heat and hot air moving around while engine is running. I even have two electric fans blowing and a 18” clutch fan pulling air for engine cooling.

I am beginning to think it is exhaust heat causing my problem. In the future going to go to cremadic coated headers, maybe even thermo wrap and change to a waterless cooling system...

Any thoughts welcome, thanks

It doesn't seem like you have an overheating engine, only a hot steering column. If that is the case, then it makes no sense to change to a waterless coolant, like Evans. As to the steering column getting very hot, I have not experienced, nor have I had anyone ever tell me, that headers transmit that kind of heat into a column. If that is the case, it might be cheaper to try a header wrap first. If it works, then look at some ceramic coated ones.
