Top Sash Guide Replacements

Home Owner from Florida
Hi,
I'm currently trying to replace all the sash guides in my house as a lot of them are broken and don't hold the balance anymore. I know the specs of the guides I need but am not sure which piece will be the best fit. I was unable to find any markings or identifiers on the sash or the guides.
The top of the guide is 7/16" deep and 15/16" wide, the body of the guide is 3/8" deep and 9/16" wide, and it's 1 1/2" tall. Crucially, the hole in the sash guide where the screw is meant to be is a full inch below the top of the guide.
Any idea which piece would fit best here? The generic Prime-Line one from Amazon fits in the sash, but the screw hole is too high and doesn't line up with the one on my sash. Any help would be tremendously appreciated.

Thanks for posting! This top sash guide has a similar design to the 18-166 5/8" Top Sash Guide. It seems to be the closest match to what you have but you'll need to compare the dimensions to confirm it is the right fit.

Take a look over the diagrams below and see what you think!

Jasmine,
That looks like exactly what I need! The dimensions seem to match what I have installed pretty much exactly. Thank you so much for your help!
