About the ign switch deal I mentioned. I can't recall when Chrysler changed the ign switch plug and setup, but while at least up to 74 was used this



On laters ( 75? 76? 77? ), the plug used was this




When not just the plug but also the wiring and the power distribution also changed. So even if the column physically fits ( which I think it does ) you will need to reuse your ign switch


I guess if you are hunting for 'Doba/Charger column you should pay attention to the firewall plate will tell you if you can install a later column into a 74 without any problem. The rest will be pretty much the same fitment and bolt in
