Top hose = easy. 45deg bend out the thermostat (with 8mm take off for header tank)into a 450mm long straight bit of ali pipe, then some flexible hose into the top of the radiator which is at a jaunty 20deg angle.
Bottom hose = difficult. Loads of posts on the cobra forum about this, hoses going under the steering rack, very close to the floor, or alternatively hoses going through the middle of the camber compensating rods. After an hour of blue petering we arrived at a compromise solution, made even more difficult by the fact that the lower engine water outlet is 45mm, the radiator is 35mm and the fan switch I bought is 38mm.
Eventually, we came up with the following route: 90deg 35-38mm elbow out the radiator straight into the fan switch. That goes into a 90deg 38-46mm elbow which takes you onto the fore/aft alignment, roughly in the centre. 150mm ali hose joiner into a jauntily angled 45 deg elbow that takes you OVER the top of the steering column. Another short straight hose join (with a 3/8 tapped hole for the 16mm ID header tank take off) to a 45deg elbow, another very short hose joiner (76mm from Merlin is their shortest standard length) into another 45 deg elbow to get you onto the lower water inlet of the engine.
