1968 Valiant 3 speed

when the parts are correct;
the ball-ends will locate the Z-bar parallel to the ground and at 90* to the vehicle's centerline.
The outboard lever will locate the downrod from the clutch pedal in about the center of the firewall window.
The freeplay adjuster/pushrod will connect the inboard Z-bar lever to the TO fork, in such a manner as to be about parallel to the ground in side view, and parallel to the centerline of the vehicle in plan view...
With the freeplay adjusted,the TO fork should be near the forward edge of the window, leaving just enough room to install the rubber boot.
There should be an anti-rattle spring pulling the TO fork forward towards the engine in such a manner as to pull the TO bearing OFF the clutch fingers.
The over-center spring, under the dash, should pull the pedal back up off the floor, and onto it's stopper.
You can run as little freeplay as you like, as long as the TO bearing stays off the clutch fingers. If it gets to spinning full-time, it won't last long. The norm is 1 inch.
Clutch departure should be adequate at .080inch

IDK for sure but I think the short fork (10.5) fits the early As and 9.5 inch clutches.
Most other A-bodies with the 10.5 clutch, use the 12.5 fork
