Alistair spotted the killer blow - a stone chip just mm from the top dead centre which has sadly triggered a 6 inch crack which is growing slowly down the screen. It's going to break in half over the next cobblestones

So...question is...where best to get this done? I'll be using my insurance obviously, but am aware the front clam needs "slackened" to ensure access to bond the base of the screen properly.
MMC?
Favoured bodyshop?
Planning to phone Craig at MMC on Monday now, but thoughts welcome.
