Please help me match this 5/8 inch wide sash guide for replacing in 7 of my windows. Home built in 2003.

Hello,

Take a look at the 18-171 top sash guide. The top is longer than yours, but you might be able to use the top hole to lower the guide under the flange, or you may need to cut the top down to match your original guide. See the specifications below. Thanks for posting!
