when I bought the truck (66 C10) I found the turn signal arm that sticks out of the column laying on the dash. I have not taken the steering wheel off to look but I am hoping someone can give me an idea of what is broken inside. Is it the turn signal switch, the turn signal switch cam or the turn signal switch cancellor. Im guessing what ever is broken is what the turnsignal arm is screwed into. I was hoping someone else might know so I didnt have the column torn apart while I waited on parts. Thanks.
