Top sash guide ID?

A handy person from California says:
Hello, this is a top sash guide from a SunAir window. Can you tell me which part replaces this?

I've tried to be as exact as possible on the measurements.

Thanks very much,
Tony P

Hello again, Tony. The closest match we have for this top sash guide is our 18-036, though it's not exact. Do you think you could get this to work? You may need to drill a hole in the top portion, since ours does not have a hole in the same spot as yours.
