Header Tank & More Hoses

More progress on the cooling system. I've now fitted the Header Tank and secured all the hoses with stainless hose clamps:
The header tank was fitted the top engine bay brace with two M6 rivet nuts and bolts. These do not take a great deal of load as the tank rests on the cross brace and is effectively held in place by the hoses.

Having fitted the headers it has become clear that another problem has surfaced. The spark plug boots under the outer two pipes on both sides are only about 10mm away from the pipes. This may be too close for comfort and may mean that I need to wrap the headers (this would also help with the oil cooler pipework which will also run close to the headers) - Looks like another question for Andy at GD.
