I dont want to break anything since there are hardly any fc's at my local junk yards...anyways i can seem to figure out how to remove my ignition switch....i unscrew the 1 screw then disconnected the harness(at the bottom) except 1 the one on top connected to the ignition cylinder i guess thats what its call...there are no screw its like a washer thing only...i search but only found the one back in 2004 with the chilton website....

 

I remember taking a switch out of a first generation once. No heads on the attach bolts. i cut a groove in the middle of the thing with a dremel motor and then screwed it out.

Or was it a pair of vice grips I used? Got me. Just a couple of ideas.
