Last week, I ordered and received your part #18-008, a 5/8" top sash guide. Turns out to be the incorrect part. Can you please help with the correct part, using the two attached photos? Thank you.

I'm having trouble finding a match for this. May we have the depth of this top sash guide, and a photo of how it installs in the sash?
