Larry, look up the term 'steering column
lock' in the archives. My post had some
informative replies. I had mine changed some months ago and Benzmac is correct to change ALL parts. Plus when you buy the tumbler
you can go the extra step of having it keyed to the original key otherwise you will have a
different key for the ignition (like me).
Good Luck. I saw it done. It's not that bad
of a task but can get tricky getting it all
to set in place and come together.
