Hi there!

Thank you for reaching out to us. Our Series 770 looks like it'd be a good match. Can you confirm the length of the metal channel and the exact weight of the window sash? That will help us confirm the correct length and stamp option for your replacements.

If you need the pivot shoe, take a look at the specifications for the 15-129 and see if they match what you need.
