OK, I have stuck a paper clip in the little hole & turned the key in every posistion I can think of, how do ya get the key cylinder out?? This is on my 66 C-10, I am using the key out of my Chevy II to turn the cylinder but I can't get it out. I have done it in the past with a new switch & tumbler off the shelf but that was with new parts. I have a new cylinger & it has 2 holes in the face of it which is really interesting...any help out there?
