Crank arm and track broken

Question

Hi!
I need to replace the mechanism to open the window and the track. Both are broken. The screw holes are also stripped in the window itself. The part numbers I can see say Truth 30905, but I can see a number on the track. Could you please help me figure out what I need in order to replace this? The window is currently unusable.

Hello,

Thanks for your post! This window operator reminds me of the 39-171 Truth Hardware Dyad Operator. I'm fairly certain this should be the correct replacement but be sure to carefully look over the design and specifications to be sure.

The compatible hardware and accessories can be found tagged below, along with the opposite version of the operator.
