Got mine done by a lock smith, total cost with two keys $14.35. On my 55 ignition switch comes out by just removing the ring. On mine all three locks are different. But they can be fixed by the smith. I haven't done that yet. I could get a used switch for about $25. My locksmith had a key ring with hundreds of chevy keys. One fit and works perfect. My next door neighbors 65 chev has the bezel on the switch. Its pressed on, he popped it off and pulled the switch and popped it back on with a little re-bending. Best route? I don't know.
