1970 Datsun 240Z — windshield replacement created a highway whistle — Bay Area owner question

TrackRoadie11Community StarterMar 7, 20261970 Datsun 240ZBay Area

A windshield was replaced and now there is a whistle around highway speed that did not exist before. Glass looks seated. Any simple way to locate the air leak before taking it back? If I figure it out I will update the thread. Mileage is about 67,000.

Before you spend money, owner data points help more than a generic forum diagnosis on a 1970 Datsun 240Z.

If it were mine, I would verify the cheap/easy branch on the 1970 Datsun 240Z before committing to a big repair.

I would start here: write down what you already tested so the next step is not a repeat.
