Replacement for window crankshaft

Question

Existing hardware: 3061430893 (pictures included of old and new crank shafts)

We are currently in the process of replacing our window crank shaft for a window upstairs. The old crank shaft is measured at 4 3/8 inches in length. The replacement crank shaft I purchased is 5 inches and does not fit properly. Is there any way we can get a crank shaft at 4 3/8 inches. If not, please advise.

Would also, if possible, like to send the 5 inches crank shaft back.

Thank you, Patrick

I'm afraid they don't make this operator with a smaller arm like you need, but we do have a solution. You can drill off both arms, then install the old arm on the new operator using a 62-014 rivet. That is usually what I do when presented with this issue and I find it works well.
