Hey Mark. We don't carry this exact Top Sash Guide, but we believe the newer style Alenco 18-174 might work as a substitute. The screw hole is 11/32", the width of the body is 5/8" and the depth is 9/16". The balance locking lip is 1-7/32" down. This looks like it could work but take a look and see what you think.
