I have a 3 speed on my 1969 F-100.. I cannot move the shifter.. Frozen. Links below disconnected. Still won't move. Removed steering wheel etc. The sleeve won't move. Tried blaster and set over night. Nothing. At this point I'm afraid to force anything for fear of breaking it.. These parts arn't cheap..I need help .. please.. Does the sleeve move up and down with the shift lever.. Is there some sight I can visit with some visual images and how to or what not to do?? Thanks fellows.. Bob
