This is where I get lost, do you mean to remove the slave from the
bellhousing and push the piston back? On a 77 midget, I cannot seem
to figure another way of doing this, as the rod is not exposed.

I'm having a heck of a time bleeding my clutch. I've tried to use a
mighty vac on the bleed screw, but to no avail, yet. I know this
subject has been hit on here and there, but any suggestions will be
greatly appreciated!
