You can see the Black Rubber cover over the "T" shaped adjustment handle.
(AND the "Nipple" for the Vacuum Hose/Line [Cable] )

These are sideways pictures,the only visible portion on the Automobile will
be the "Brassy" ring (Outer Circumference) and all portions to the Right in the
Picture.
No view on the car of the O-ring and White Plastic,they'll both be
stuffed into the Transmission itself.
