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!
