Is there a Clutch/Starter interlock switch on an 82 GT?

Well i can't tell you if you have one or not because i really don't know about your year car (i know later ones have the switch on top of the clutch pedal if i'm not mistaken) but an easy way to find out is to put it in 1st gear, put throttle to half way and try to start the car [make sure you're on a road with space ahead ] if it starts lugging forward and/or starts and drives then you don't have one.
