45012 - Crank Handle & 30744 Truth - Crank Assembly

A home owner from USA says:
I have a casement window where the threads on the crank are stripped and it needs to be replaced. The information I got off the handle and the assembly are:

45012 - Crank Handle
U.S. Patent 4,083,264

30744 Truth - Crank Assembly

Can you tell me if these are the correct part numbers and how I can order them? Also, are there any other parts needed to replace the assembly. I did watch the youtube video from your site showing how to replace this, especially the part about how the trim piece can be pried you to access the hidden screws.

You could possibly have our 39-013 operator, but I cannot be certain. The best way to know for sure is to remove your operator from the window and carefully compare it to the pictures and dimensions we show on the 39-013 store page. You can also place your order directly from that page.
