Those early GM tilt columns are notorious for the issue. I think there are 3 or 4 screws that mount the top to the tilt plate and they always work themselves loose. You will need a special tool to compress the spring to disassemble the upper part of the column. remove the turnsignal switch and the screws are in the plate underneath. Its been about 15 years since I have done one so anybody correct me if I am wrong.
