Window Top Sash Guides

Question

The photos show the dimension of the sash guide for my window. There is no part # and I don't know who the manufacturer is. Thanks.

This is an older type of top sash guide, but I think our 18-171 can still work. Service people have used this by cutting the top section down a little. It goes under the sash top rail, so the cut won't show from the outside.
