Gregg, Welcome to our little world.
Melbourne must be the CR/GM capital of Oz. There are lots of them down there. I don't know exactly what that says about Melbourne but the builders/owners seem like a great bunch of blokes.
Don't tell em I said that 
I'll let them answer your questions.
There are some rules in here you must respect.
Rule 1. Don't take offense at what any-one says.
Rule 2. Take no notice of what an owner of a ford powered cobra says.
Rule 3. If there any dispute then rule 1 & 2 apply.
Cheers and welcome to the mad house
