My master cylinder was leaking A VERY small amount, so I put a new one in, but the problem is still the same. There's just not enough clutch. All the way to the floor and it won't go in gear. It will go in reverse if I slam it in, but the car will slowly roll back.

I know the clutch is shot, very bad, but I figure that would make it slip, I didn't think it would make it not disengage.

How much should the throwout bearing arm move? If I push in on the slave cylinder pushrod thing and my brother pushes the clutch It move about an inch, I think it's about the same when the slave cylinder is installed, maybe the throwout arm moves an inch. If this is the mormal amount my clutch is probably whats wrong ( the disk is worn almost to the rivets )

So what do you guys think?

 

The spec for movement of the slave cylinder rod is .58" - just over a half inch.

 

???? I haven't measured it, but It easily moves that much. That distance is the movement that the slave cylinder will make with the slave cylinder installed moving by pushing the clutch? If so I should have enough.
Hmmmm this just makes more questions.
Could the worn clutch disk be causing it?
Bad pressure plate or something,
Is there supposed to be a shim between the flywheel and crankshaft?

 

It was a conversion from an automatic, I'm thinking I positioned the master cylinder to low. I looked at a friends z today and it looks higher than mine. I have to check for sure tomorrow.

I drilled the holes right though the firewall using the rubber floor covering holes as a guide. Could these be too low?
