Sure thing mate. I'll some pics this afternoon.

I did contact one place that came recommended through another forum. Western Smash Repairs in Sunshine LINK

The guy I met, Tony said this is a common repair for him. He did explain what you mentioned, what you see on the outside might not be the extent of what's really there. He assured me that they'll be thorough so the problem never comes back. I thought his initial quote was reasonable and I've decided to let them work on it (in a couple of weeks time)
