I've had the same issues with my 66 IIA... Replaced both MC and slave, bled and still wont disengage the clutch unless i pump the clutch pedal... I can start the engine with it in gear then let up the clutch and get going that way but it doesn't completely disengage.
When i installed the slave there was a spacer, but i didn't install it with the new slave since the newer didn't look like it needed it, but I did make sure the length of the nuts on the pushrod were the same as the original. Thoughts?
