Clutch drag

Well, I had a little time to look the car over. Looks like the clutch pedal spring has been removed. The car has a Lakeland style belhousing so I could not see the clutch to this weekend. Took the wife for a ride and the clutch pedal felt real smooth for the first 10 minutes, then it started to feel jerky while releasing. Had the wife work the pedal when we got home and noticed the z bar bushings were turning a 1/4 turn when working the clutch. I also noticed a very very faint humming noise while in neutral when the clutch was released but it went away when the clutch was pushed in. Probably gonna start with z bar bushings and work my way inward....
