Truth Dual Arm Operator broke inside

I have a Truth 40078 dual arm with a crank that is labeled 1(possibly I)2 45054.

The operator has broken on the inside, so I believe my only option is to replace. I have a couple of items in my cart, that look close, but I was wondering if you had any suggestions.

Hello, thanks for writing in! Without seeing how the arms of your operator attach to the window it's hard to say for certain what the best replacement might be. However, take a look at the parts I've associated on the side. You will need to compare their dimensions to yours to see if any of them might be a match.

Yeah, I think what you linked is what I have selected as well.
Thank you.
