This is the best I can give you. I just put these on my 67 GTO and it was a bitch! The top return spring is the hard one, one side hooks to the z bar and the other end hooks to the body above the frame ( it is the hole just out of reach of the spring, thats why it so hard). I don't have my car here so I can't get a picture of it.
I will say the clutch pedal feels so much better with the springs.
Good luck and be careful.
