Casement Hardware

I have a double casement vinyl window. The hardware is stamped Truth. The stud bracket mounted to the window is flat and is 8 inches in length. On the window pictured the stud mounted to the window is rusted off. I should probably replace all the hardware for both the left and right windows. The length of the arm attached to the track and window is 5 1/2 inches. The length of the arm attached to the window corner and the operator arm is 5 inches. I am surprised they used SS screws to attach the operator but not to mount the track. I will also need to replace the weatherstripping and that will later.

Can you help me to find the correct replacement hardware?

Maybe I wasn't completely clear in my original message. There is a stud bracket mounted to the window that is 8 inches long. The stud is mostly rusted off. That is the piece I definitely need. That stud would connect to the hinge set. I don't really want to remove that bracket from the window because that is holding the window in place. I have attached a photo with both stud brackets shown in place.
I will be out of town this next week so anything I would do would be later.

Thank you.
