Marty - Glad it helped.
Are you running a reproduction valve or original 1969 valve?
I tend to see the same valve reproduction part listed as BOTH a 68 or 69 valve.
But folks who have the 68 AIM and original valves say its
shows the valve order as green on top, yellow, the red on the bottom.
But the 69 AIM states its valve is like traffic light red top, yellow, and green on the bottom.
I think this is where folks have gotten confused looking at 68 specs for 69, vise-versa
The actuators are identical both 68 and 69 so why they changed the valve who knows.
