Replacement Locking Mechanism

Hello,

I just placed an order number 1473555 and then realized you offer guidance here. I've attached the pictures of the locking mechanism that is broken and needs to be replaced. Can you please confirm that I ordered the right replacement (part code 82-043) and if it's wrong cancel my order and I can place an order for the right mechanism instead. The measurement from screw to screw is approximately 2.5 inches.

Thank you so much!!
Audrey
