I need to replace my ignition lock cylinder in my 85 740 and their is a small bolt on one side that holds the lock cylinder tight in the column..like a vice..the problem is their isn't a srew/bolt head to grasp its almost like a flat tapered rivit type head ..how to unscrew?? anyone??

 

Look round the back of the electrical portion of the switch and you will find two cross recessed screws. They hold the switch in place.
