Hi there!

It looks like you have either our S351-26 , with a 15-002 bottom attachment, or S390-26 , with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.

If your window sash weighs 23 pounds, then you will need a spring strength option of 2540 which represents a sash weight of 19 to 25 pounds.

As for your top sash guide, we'll need to see it removed from your window, along with dimensions, to compare to our inventory. 

If you have any further questions just let us know.
