TOP SASH GUIDE identified?

Question

one of my window channel balance spring snap and the bottom guide fell apart. I also found out one of the top sash guide also broke. the channel balance is stamp 1540 and look closest to your S380 line base on the top and bottom guides. I want to order both the channel balance and the top sash guide at the same time and need help identifying the top sash guide.

Start by looking at our 18-166 and see if its dimensions match up to yours. It's hard to make out your precise measurements based on your pictures. If they differ in any way, let me know by exactly how much.
