I have a 1980 L-82 Vette and would like to install a new steering wheel. Can anyone tell me where I can get a diagram showing me how to take apart the steering coulum and replace with a new one. I have tilt and telescopic steering. Also, my door handle has broken on the drivers outside. I need to find out how to remove the power lock button and trim and also how the door handle works. I appreciate any help.
