I need a crank mechanism for my window. Pictures are included
The flexible arm is 3 inches with the holes being 2 3/8 inches from center to center.
The opening of the mounting hole of the arm to the window arm is 1/4 inch.
The 2 lower mounting holes are 1 5/16 center to center with the distance from the mounting holes on the bottom to top being 5 3/16 inches center to center.
I believe this is a left handed crank mechanism

Enclosed are photos so please advise which crank Mechanism I need.
