Hi Greg, it does look like you need the 18-166 top sash guide and the 67-026 face guide. For the balance, please recheck the depth of your bottom shoe. We believe it is 1". If so, use the S380-30. If it measures 1-3/32", use the S385-30. Now for your spring weights, it's very unusual to use to different weighted springs, 2930 and 2940, on the same window sash. The 2930 carries a sash weight range between 16-23 lbs, and 2940 carries 23-28 lbs. Mabe the manufacturer or service technician found it necessary to use this combination for a smoother operation of the sash. Regardless, please review. |
