Months ago I asked how one removes and replaces the clutch master cylinder single-handed. I've discovered you can't .. you can barely do it with two people. But it's done .. the slave was a piece of cake. Naturally I didn't measure the threaded lengths of the old master and slave piston operating rods. Where they are set now .. on the master the clevis is screwed down to the nut on the rubber boot. The slave is set about where I remember the original one was .. slight clearance from the TO bearing when the TO bearing arm is pushed on.
I suspect that with a totally bled system I need to screw the clevis out .. reconnect the pin .. and test to see if the slave moves enough to disengage.
But I'll take advice from this learned forum. Thanks.
