Hello, The 39-257 crank is not very common so I'd recommend taking a good look at the "body" of the operator to make sure that it matches up with yours. As for the "T" handle, the 39-108 will fit the spline but the "wings" on the "T" handle will hit the body casing on the operator. This will prevent you from operating the window unless you were to cut the wings on the T handle so it can clear the operator's body. As for the link arm, it is 2-1/8" on centers from the center of the rivet to the center of the threaded screw hole. Thank you! |
