Well, over a year later i got round to replacing my windscreen! What a b!tch!
I couldn't get it out without kicking the sh!te out of it, but fortunately i didn't need it as the reason for removal was a big crack. Getting it back in was fun too. I was trying it without any string and it wasn't happening, so a quick trip to asda and one washing line later and it was back in within 5 minutes

I now have a nice green tint with blue top strip screen.

Just got to put the rest of the green windows in now!
