Norco window operator

The operator for this window needs to be replaced. It will open the window, but no longer closes it. I've removed part of the window casing to expose it for these pictures. I am reluctant to completely remove it until I have a replacement as I'm not sure what would hold the window in place. It's a second story window. I'm thinking it appears similar to 39-031. What do you think? Open to any advice..

Just measured my right arm. Mine is 3 13/16" long. Yours is 4 7/16". Not going to work unless you have another option I'm not finding. 20755 is stamped on this arm. Stamped on the connecting arm is L30841. The operator base has 4047, Truth and 8 stamped on it. Still working on complete removal.

Removal success! Here's a pic. The long arm is 10 3/4". Not sure if a 1/4" is a critical difference.

Thanks Tom. That looks to be a much better match on the link arm side. What do you recommend for the other arm with 1/4" difference?

Actually, I just ran back and measured ours, and it turns out the length of the arm is 10-3/4", as well. The measurement we had was a typo. Sorry for the confusion!

You guys are Rock Stars! Thank you so much for helping me discern which operator to order, in such short order. Just ordered one.
