Ford focus heat shield - exhaust

[thekingisdead]

Slightly bizarre question this.

I need to remove the heat shield off a mk1 petrol focus (over the backbox of the exhaust) except the car is at my mums house, some 80 miles away.

Does anyone know what type of fixing it is? I'll take make complete socket set obviously, but would hate to find out its an obscure fixing when I get there, and I don't have the right tools.

Thanks.
