Thermostat Housing Desperately Needed

[Allyc85]

Just had one of my mates on the phone saying his Mk1, 1.8, petrol Focus is peeing coolant out of the thermostat housing, and that he needs it fixing before going away on Wednesday morning!

its a massive long shot, but I was wondering if anyone knew where we could get one, preferably as close possibleile to Newton Abbot in Devon.

Cheers
