I don't understand just what you are saying in your last comment, 10X.
If you are asking about where the TUL hits, my first picture shows where the end of it hits the bottom opening of the faceplate... I haven't tried turning the screw you point out because I do not see where it could possibly alter the angles of the TUL end by moving the whole assembly away from the hand wheel and towards the faceplate...
Any ideas, Glenn?
