Got some silicone hoses in the post yesterday and set to making all the water connections. This time I've run the bottom hose down the outside of the chassis in the gap between it and the body. I've run the hose through a tight gap between rad mount and chassis and am hooping it won't cause a problem. Its all solidly mounted and shouldn't be moving around.

Hoses going round outside of chassis.

Top rail is now secure thanks to some correct size reducing hoses and the tube is fastened to the engine with a home made ali P clip. Heater outlet on the back of the thermostat housing to block and it should be ready for some antifreeze. Next step is the oil filter housing to make oil tight and get some new oil in.
