I need to purchase 3 right-handed and 3 left-handed window brackets. The part in the photo has 31850 on the arm and the crank housing has 45251 on the bottom. Thank you for your assistance!

This reminds me of our 39-171 and 39-172 Split-Arm Operators. Please compare and see if they match what you need.
