Start by looking at our S385-28 channel balance. This appears very close to what you have. It comes with the 19-005 top and 15-004 bottom, so as long as those match what you have now you should be okay. I'd also recommend the 2740 spring strength option.
As for the top sash guide, we don't have your exact style but we do have the 18-161. You will need to cut down some of the top to fit under the vinyl sash. What do you think? |
