Top Sash Guide

A home owner from san diego says:
Dear Customer support team.
Attached are the pictures of the top sash guide we have. The part is close to 18-008 or 18-008H but there are few minor differences such as the shape of the top portion. The length from the top surface to bottom hole is 1 5/8", the width is .6". the depth is .58" which is slightly more than the depth of 18-008 which is 9/16". Can you please let me know the correct replacement part?
regards, Sanjay

Hi Sanjay, thank you for posting,

Your top sash guide looks to be a better match for the 18-171. Please review the overall dimensions to confirm a good fit! Let us know if you have any additional questions.
