Just getting my car back together. 73 Duster 440/4 speed/Dana 60.Car hasn,t been driven in over 1 1/2 years.The clutch was stuck to the flywheel, so I pushed it out of the Garage put it in first gear with the clutch pedal pushed in and bumped the started.After 3 or 4 tries it released so I drove the car thru town and on the highway for about 20 minutes.Felt like all was normal.Get in the car today and the same problem is back. When I push in the clutch it feels like its not engageing the pressure plate(no resistance)Crawled underneath and all of the mechanical linkage is working properly.Feels like the pressure plate is not pushing back.Tried bumping it over in gear with the pedal depressed, but it will not release. Any ideas? Thanks, Dave
