17 year old Rivco window

Thanks for posting. It's possible your pivot shoe is the 15-167, but without seeing it removed from the window and knowing its width and thickness, this is just an educated guess. Please remove the shoe and compare with the dimensions below to ensure it matches what you have. Let us know if anything differs.

The tilt latches might be the 26-243 and 26-44 pair, but again, we advise removing one and comparing with the dimensions below. Let us know if anything differs in any way.
