Gas pedal slack. Help!!

I have a problem. Its pretty lame that when you smash the gas to the floor, that your not hitting WOT :bang: . why? there is too much slack in the gas pedal. if you look at it, u should be able to lift it up at least an inch to an inch and a half. I want to be able to hit WOT, not 60%or whatever it is. so, does anyone have any tips on how to take out the slack on the gas pedal of a 89-93 5.0? anybody?
 
Are you basing non WOT on just judegement or seeing this? The trick i've used before is using large zip ties around the cable past the pedal but before the stud. This will take a good deal out of it depending on how many you use. BUT, if you go overboard than you'll put too much stress on your throttle body assembly and possibly break the spring mechanism or wedge the butterfly plate from over-extension.
