Ok, there should be a vertical cap between the sides of the goalpost moulding and the glass... this is built into the frame to allow rainwater to flow up and off the screen at speed as the wipers clear it.
But yes, the frames and mouldings are all attached to the new screen prior to fitting. This allows the moulding to set the location and depth of the screen.
Dave, you screen looks to be set wrong in both position and depth... almost looks like they went to fit the trims afterwards and pulled the screen out of the aperture trying to get the trims to fit, obviously failing miserably.
If you can get the new frames and mouldings from VX then I would suggest that, otherwise get Autonoglass etc to supply it, watch them like a hawk and refuse to accept it if it doesn't look right, don't fit everything in the correct order or only send one person.
The Omega requires two people to fit the screen correctly (from Autonoglass following their second call back).
Think we covered the whys and wherefores both at that meet and in recent posts
