Thanks for reaching out! We do not have an exact replacement for the top sash guide you have pictured here but our 18-008 or 18-008H may be worth considering as a replacement. The side profile measurements are the same for each of these parts but you'll need to be sure to confirm the installation hole measurements to determine which may be the best fit. Let me know if you have any questions.
