Hi gentlemen!, I have a 1990 F-350 5 Speed hydraulic clutch system. Clutch takes hold about an inch off of the floor. I have checked both master and slave cylinders, no fluid leakage in boots, no fluid loss in reservoir, no starting to creep when clutch is held down, bushing is good at clutch linkage under the dash, very very little flex at firewall. Any ideas? Any way to adjust anything to get more pedal? Clutch pedal comes all the way up to stop as it is supposed to when you take foot off of pedal... hard to get in gear, grinds usually going into reverse...
