Hey, i looked in to buying a kit but struggled.
i ended up just buying a oil cooler and sandwhich plate similar to this link
www.staparts.co.nz/View-A-Product?id=4875&Productid=Oil%20cooler%20kit%20black%2010%20row%20-10AN%20fittings%202%20x%201600mm%20length I mounted my sandwhich plate directly over the factory oil warmer/ cooler, filter basically stays in the same spot, just sits out a couple inches more which is no hassle. Mounted the cooler where yours is. grabbed some old shitty hose and bent them into the path i wanted just for a mock up. the ordered the fittings and hose etc Mount your cooler and sandwhich plate first, then its all striaght foward from there.
