ignition trouble
 

I have a 1981 ford F250 custom with the 300 I6 engine. Its in pretty tough shape because it's been converted and used as a feed truck on our ranch, but has been parked and not run for probably almost 8 yrs. Anyways, i got in it the other day turned the key and my ignition turned 360 degrees with no resistence what so ever. i haven't taken the steering wheel off or anything i wanted some advice before i get to far into it.
