Audi 80 Cabriolet - Water leak around windscreen

[RogerMac]

I have recently been in the market for a cabriolet and on one occasion liked the vehicle but was concerned about water leak by the windscreen over the fuse box. The owner had done a DIY fix with tape and plastic but in the end I decided not to buy in preference to another vehicle. The one I have bought is in good condition but there is no cover over the fuse box as can be seen from the photo. Water would appear to be able to run down the windscreen into a plastic scuttle which runs the full length of the windscreen and straight into the top of the fuse box. The off side (RHD) has a protective plastic cover.

Do I need to be concerned?

Is there a cover I can buy or get manufactured on a 3D printer?
