Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, these a little more difficult than most and will require some special tools to do. You will need a steering wheel puller, a lock plate depressor and a lock tool for the telescoping steering if it is equipped with a telescope type of wheel. You will need to remove the steering wheel, the lock plate and the turn signal switch to access the warning switch that makes the key buzzer work, then you can get to the screw that retains the lock cylinder in the column. I am sending you some information on both the standard column and on the telescope type. If you have questions, just ask. You should be able to rent the needed special tools from most parts stores. You may want to print this stuff out. Thanks

To remove the wheel for turn signal switch service, follow Steps 3-6 "Standard Wheel" procedure. Tighten the nut to 30 ft. lbs. On 1975-76 models, it is necessary to remove the snapring from the steering shaft first. Dont forget to install the snapring after tightening the nut.

YOU DO NOT NEED THE TURN SIGNAL SWITCH ALL THE WAY OUT OF THE COLUMN, JUST LET IT HANG BY THE WIRES.

Considerable force may be necessary to break this casting flash, but be careful not to damage any other parts. When ordering a new lock cylinder, specify a cylinder assembly. This will save assembling the cylinder washer, sleeve, and adaptor.
the illustrations that you sent are not legible. what publication did they come from??
They are from an Auto Zone book that I have and one is from a GM manual. I will try to enlarge them and see if it helps. These are from a couple years newer, but should have what you need, if I can get them to post. Thanks
Your switch, may not have a screw in it, it may have the push in detent like in the other picture.
Looks like that is about all that I have, have you tried enlargeing them on a printer?
