39-058 with 2" long extension arm?

The window is made by Palm Beach. It's probably 50+ years old. Right hand crank is missing, and trying to replace it. Took one off another identical window. There are no markings on the operator that I can see. Several operators you have are almost identical (attachment holes spacing, etc.) except the length of the offset arm extension is too long. For example, your 39-058 matches everywhere except the arm extension is 2" (hole center to rivet center).

4 holes mount it. Bottom 2 are 1 3/8 inches apart, center to center. Top 2 are 7/16" apart, center to center. Offset extension arm is riveted on the left side of the geared arm (looking at it from behind, or from the crank handle edge) and has a 3/8 inch diameter hole in the other end of the extension arm. But the measurement from the rivet to the hole in the extension arm is 2" exactly.

Do you have one with those dimensions, or can you suggest a remedy?

Thank you.

If you are certain that all other measurements match up to yours I don't believe the link arm will be a problem. It is only 3/8" longer than yours and the travel in the linkage and gearing should make up the slack in the length. Just make sure all other dimensions are the same as yours.
