I've got two windows with broken crank assemblies which I'd like to fix. Pictures attached. The crank handle has the number 45012 on it.

Greetings -
We can absolutely help you with your broken assemblies. Carefully compare what you have to our 39-155 window crank. I think this should be a good match for you, but let us know if you agree!

I got the part and it doesn't fit! It's clearly very close to being right, but not quite. I pulled the old mechanism, and here are some numbers and measurements;
The long arm is stamped 30470 L.H. and is 9.4" from the right-angle bend to the end of the arm.
The piece of the short arm closes to the gear is stamped 30849. It is 2.6" from the center of one joint rivet to the center of the other rivet.
The piece of the short arm which attaches to the window doesn't have an obvious number stamped on it. It is 2.85" long, 2.35" from center of pin to center of pin.
Help!

Yes, that seems to match it. I'll order one.
