I am enlosing both side of the piece needed. Our windows wont lock in any more after cleaning. I think two numbers may be on the underside, 21 and 092. There is also a pat. Pending number, but that didnt get any results in an internet search.

Start by looking at our 26-391 and 26-390. Carefully compare our dimensions to your own before you purchase anything, though, just to make sure they're the same.
