The windscreen is now back on for good and I've fitted the escutcheon plates around the bottom of the screen legs and those for the windscreen demist vents. The plates around the bottom of the screen were bent slightly to match the curvature of the body in this area and the holes through the body and the underside of the plates sealed with clear silicone. I've also fitted the demister "funnels" (?) which fit under the vents and direct the air onto the windscreen. These are held with the same bolts which secure the escutcheons so the two are done together. A little tip for anyone approaching this stage, I had trouble getting the bolts to screw into the threaded bolt holes in the "funnels". This was due to a layer of paint which had built up so I ran an M5 tap through them to clear them out which made the job so much easier.
