Top sash guide for Gapco Window

A handy person from chicago says:
Hello,

I am trying to identify a top sash guide for a gapco window. I think this is the one that works with what i have provided pictures for. I see that the style has changed and i wanted to confirm the new style will work with my old style. Please see attached pictures to verify my needs.
Thank you

Thanks for posting! This looks like the older style of our 18-156 Gapco top sash guide. Do you think that would work for you? Let me know!
A quick learner from Chicago says:
Nope, this one didn't work for me. I have the same sash guide as pictured above and I purchased the 18-156 part to test it, and it does not stick out enough to hold the channel balance. Notice the blocky square part sticking out on the photo above - that extra width is required to grab the channel balance.
