1965 Dart dash question

If its like my barracuda the headlight switch has a button that you push it to release it. It is on the switch assembly so if you can feel around or look up under the dast you can see it. Mine was red and easy to see, after someone told me how to do it. The wiper knob had a set screw to release it. Just twist it like your turning on the wipers and you will see it on the side.
Hope this helps.
