Here's the link to the regulator I bought. (I got it from Amazon.)

Also: Per hrtbrknprince, I suppose it's possible that your rattle issue comes from a loose fastener. But if the symptom stops whenever you lower the window, even a tiny bit, then I'd bet it's the regulator. I had taken apart my door and tightened every single fastener, and even used locktite, but the noise persisted until I replaced the regulator.
Good luck!
