Water leaking issue

[Dekrypted]

So i have been having an issue with water leaking onto the driver's side floor in my 04 Grand Prix so I took the cowl off in front of the windshield and noticed that it's missing the plastic cover over the driver's side windshield wiper motor. I tried calling multiple auto stores and junk yards and can't seem to find it. Can anyone tell me where I would be able to find it or how I could make my own?
