I need some help my Alt static source valve is leaking failed during a static check I have a 69 M20E and my parts book dose not show one all thou it dose show a placard which I have for this type of valve The valve sticks down through the bottom of the instermint panel near where the yoke shaft gos through the panel the valve has a tee handle that you turn 90 degrees to change sources I talked to Lazer no help . I was wondering if this valve might be on a newer E or newer model . I some can find a part number that would really help me out
