Thanks for contacting us, David. First, I would double check the nylon ends on your balance to confirm that they are the same as those on our S380-29 channel balance. I would also compare the 18-180 to an undamaged version of your top sash guide. There aren't any stamps or numbers on your window that correspond to the hardware it uses, so it's not a good idea to go off those numbers alone. The only way to know for sure what hardware you need is by comparing physical dimensions and design.
As for the face guide, start by looking at our 67-026. This might be a match, but see what you think. |
