Glad your replacement went largely ok Richard, I'm surprised the A pillar trims weren't just a standard part of the job (waiting for these to arrive was the cause of my short delay).
To update on my replacement, it was not entirely smooth...
The screen itself seems fitted well, as do the rubber seals and the drivers side A pillar trim. However, the passenger side trim is not engaged at the top, it's lower than it should be and is very loose (picture below). Autoglass called me about this straight away explaining they'd tried three times to get it to sit right, with different technicians, and they couldn't do it.
I'm now waiting to hear from the warranty side of the insurer and I'm expecting them to cover the work required to correctly fit a new trim piece. I drove the car immediately from Autoglass to Allon White for them to provide a quote for this.
As I was writing this, I noticed what appears to be a new chip on the edge of the roof. I'm asking Allon White to confirm this (the car is with them) and provide a quote for fixing this as well!
The debacle continues.... at least the screen itself seems to be fitted well.
