Okay, Ive went through 2 of these..... the roller bearings shot out of both of them. I got a new one today. Im trying to install my lock cylinder in my ignition switch. It is a 1968 Mustang. How do I do this? I can't seem to figure it out. Ive tried pushing that pin down, and all that other junk, and I can't seem to get it in. I don't want to screw this one up. Please help.
