I installed a 28" series 395 Channel balance, Option 2740, on my Alenco window last year. Now I need the top sash guide. Do you know which one will fit. Mine is brown and square. It is 1 1/4" high and 7/8" wide.

It's tough to make out exactly what you have while it's in this condition, but see our 18-174 to start out. This looks similar in design and is used for Alenco windows. I'll share its specs below for you to verify.
