Windows should be adjusted to "fall in" towards the interior of the car. This is to allow the window to contact the rubber seals on the hard/soft tops then rise up into them as the door closes.
Test procedure:
- Put window down.
- Put top on car.
- Open door.
- Put winodw up.
- Slowly latch door.
You should see the top edge of the window clear the outer edge of the rubber seal, then as the door is latched, the window will contact the inner edge of the rubber seal and be pushed up into the crease of the seal. This makes the wonderful water tight condition that was so rare on roadsters of the 1960's.
If your windows do not do this, then put the hard top on and adjust the windows, then put the soft top on and adjust the soft top to the windows.
Modern German roadsters use an electronic solution. When you pull on the door handle (from the inside or outside), the power window is dropped about 1/2 inch (12 mm) or so by the motor. When the door is closed, it goes up that last 1/2 inch to fit nicely into the rubber seal.
