Electrical woes
All I know about the subject is the wiring in these old cars is very fragile and when you dropped the column something got tweaked or pinched. I would start by loosing the column back up and retracing your steps. I have had wires pinched or broken before and they are very difficult to spot you may have to start unwrapping tape if there is any. Just my opinion hopefully it may be of some help.:burnout:
