Thanks for your patience. Let's start with the corner, first, since I'm a little more confident as to what can replace that. I would start by looking at our 95-205. Carefully look over our information and measurements to confirm that this is a replacement. I think it just might be.

I don't believe we can replace that second white piece. At least, not by itself. I suspect it's part of a larger mechanism. If so, I'd like to see that mechanism removed from the window. I can't be sure we will have a replacement for it, but the only way to know for sure is to see it. Let me know!
