Why is the MB/GPW windshield frame dented in the front near the top on the driver’s side?

This dent is the only way you can remove the inner windshield frame from the outer frame. If replacement or repair of the inner frame is required, you open the inner frame fully and slide it toward the driver’s side out of it’s hinge channel. I have had customers in the past who actually welded this area in, thinking it was not correct.
