Hello,

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need to follow the  chart on the balance product page that explains how to choose your option based on the sash weight.

As for the top sash guide, you can start by comparing the dimensions of our 18-147 and 18-165 to yours. If your measurements differ, please write out your exact dimensions and we can go from there. Thank you and let us know if you have any other questions or concerns.

Your new photo makes me think that the 18-166 might be a better option. I'd recommend double-checking your dimensions against the ones listed on our product page to confirm if this could work for you. Thanks for posting!
