rattling in windshield or engine?

just replaced my front and rear engine mount. Got rid of the rattling noise in front when the engine is not getting enough gas to accel. Problem is, there is rattling noise when I’m accel. to 1st gear, 2nd gear and 3rd. Sounds like its coming from my windshield but im not sure. Anyone has the same problem here?
My windshield doesnt look too loose to me. Any comments to solve this? thx.
