You can make the lines up yourself - piece of cake. Just work out what you need. If it's going in a similar place to where mine is I reckon you'll need 2x 90 deg for the top of the cooler and then you'll probably get away with either 2x 45deg or perhaps 2x 90deg coming off the original lines to get them heading in a decent direction. Beauty of the old fittings is that they are already on rubber hoses which will help you direction wise.

Forgot to add....I'd still look at running a thermostat too.
