Window replacement parts

Hello there. I am afraid I do not recognize these parts at first glance. Can you show an undamaged  version? Can you show us where they attach and give us an idea of what they do? We'll do our best to help from there.

Thanks for getting back to me. The 26-256 pivot bar retainer and 26-465 pivot bar would be a good place to start. Take a look and compare the specifications below to intact versions of your parts. Thanks for posting.
