Top Sash guide Alenco window

A handy person from 76051 says:
I am looking to replace Alenco windo top sash guide. 18-174 is similar but overall height is different and the profile is not the same. Can you advise if 18-174 is the correct replacement or is there another part that is correct replacement.

Thanks for writing in. This Top Sash Guide looks more like our 18-009, which is also used in some Alenco windows. Take a look and see what you think.
