As Freddy mentioned in my project D you'll c where I mounted my cooler.... from there I basically run the lines under the subframe but above my power-brace then to the cooler...
They are a little bit too long, but I made sure my pipes make nice and big turns and that there is lot's of place for flex, remember your pipes will also move as oil-pressure increases...
If you want to come have a look I'm in Centurion your more than welcome... I'll check if I have any pics of the lines
Remember after installing the cooler and before you start the car do the following...
* The Fittings in the adapter plate, put some thread tape on it! Turn them out of the aluminum adapter put thread tape on and fit them back.
* When fitting the lines to the cooler, put some multi-purpose grease on the adapter-fitting and the oil-cooler's fitting this will help with the initial seal
* Fill your oil-cooler up with oil to prevent the car from oil starvation.
