All done. The screen arrived earlier than expected and got fitted at the O'Brien workshop in Osborne Park last Thursday.

Sensors all work, no noise, genuine part.
They assured me they had all the right clips to but the side trims back, and having tested them, they seem solid enough.

After my fears of a dodgy job, I'm pleased it all went so well.
Now I have the pleasure of a crystal clear windscreen, I realised just how pitted the old one was.

Thanks all for your input and advice.

Hopefully I want have to do this again.
