Sorry Graham, only just read your PM.
For the rear hoses i'm still using the Phantom original ones, however over the next year I will swap these to a couple of silicone bends I think, as Chris has had one of his rear hoses fail last year and I don't want to risk that with the price my engine would cost to rebuild.
For the front hose, a Pug 206 is the correct sort of shape to get from the chassis tube to the radiator.
As for the exhaust gasket, have you got the flange off the car? If so pop down to your local exhaust place, they usually have racks with all the different types of gaskets and rubbers etc.. on, that's where I got one of mine once.
