Thanks for reaching out to us! We do not carry an exact replacement match for the type of top sash guide you are have; unfortunately, yours is no longer made. That said, our 18-009 might be worth considering as a replacement.

You will need to trim down the edges from the top of the guide to install them. Take a look at the measurements and see if this could work for your repairs.

Please be aware that any altered parts are non-returnable.
