I am afraid we do not offer this exact part, but there is a possibility we may be able to offer a substitute. Could we have you send us another photo showing where this part fits into the window sash? From there, we will see if we can locate an alternative for you.

Thank you for the additional photos and information, Doug. We do offer our 87-197 top guide, however, it is a bit more narrow compared to yours; particularly, where you have the 3/4" flange, ours measures 7/16" and the short side of yours measures 1/4" where ours is 1/16". I encourage you to review our part carefully, and get back to us with some thoughts.

Thanks for getting back with me... I'm confused and not sure what to do... the Guide you are showing me sure looks different... it's hard to know how it will work until I have one in my hand with the window... I do not want to buy a bunch of them then them not work... I would like to buy/try one but do not want to pay to ship just one... let me think about it then get back with you... Thanks again for all your time and help solving this situation, db
