Convertible top does not close tight enough

[986lp]

Hello,

On my '99 Boxster the previous owner replaced the original top with one that has a glass window, and it appears it wasn't adjusted correctly. When closed, the top seems to not meet the windshield frame tight enough because it rattles a lot and there's a significant amount of wind noise on the high way.

Here's a photo of the gap and a video showing how much I can move it around.







I released the top from the transmission (red ball joint) to close the top manually in the event the pushrod was preventing the top's forward motion, but the fit is no better.

What should I look at next? Also, before latching how close should the top be to the windshield frame?

Thank you all for your help!
