Have you seen our 39-539? Check it out and let me know if you can use this as a replacement hinge.
A quick learner says:
I only need the black part, which I think is called the sash guide slide.Is it possible to get just the black part?

I'm afraid the manufacturer does not supply the black part by itself. We tried getting it before with no luck. Sorry we can't offer that to you!
