My windscreen is cracked and since VicRoads insist that I need a windscreen I thought I'd try to minimise the chances of it instantly cracking again.
I did a quick search and couldn't find much on string aligning your cobra windscreen.
rather than type a couple of thousand words...
It's a handy technique courtesy of my little brother that I had not heard of.
the idea is that the string should cross in the centre and just touch.
