I've got a 99 f250 with a 93 12v and the getrag. My clutch isn't fully dissengaging, but real close. I can get it in gear, but takes some force. I'm using the superduty master cylinder and 93 dodge resevoir and slave. I bench bled the system and have no leaks. I don't know if the ford master doesn't stroke quite enough or if my slave is just tired. Any thought b4 I buy a new slave?
