windscreen

I need help diagnosing a noise that's coming from my windscreen area. It's something I've experienced for a few years but just recently was able to get a video of. I've attached links below. The only difference between the two is the length and POV. The noise is pretty evident, but it's best...

I have a cracked front windscreen (not repairable) and none of the regular replacement windscreen companies have a screen. Do any UK owners have any ideas about where I can get one other than from Honda, where the price is about £500 and a very long wait for it. Many thanks.
