2007 NBS Radiator Swap Question

Ok, i got a radiator and efan setup from a 2007 NBS truck that im gonna swap into my 03 to get the factory efan setup, i noticed that the rad has an oil cooler in it, and my stock one doesnt, not sure if ive ever seen a 99-07 classic with a factory radiator mounted engine oil cooler.

Is there a factory hose setup available to hook up the oil cooler in the rad, or what parts do ineed to hook it up?


I dont think i really need it, but i figured since its there might as well try and hook it up.
