I agree. Do it for looks only.
As for the
oil cooler, I would not hook that up at all, even for looks. The
oil will frequently stay too cold to work properly, you'll have a pressure drop, and you'll waste energy pumping the
oil around. Install it with whatever lines you like, but terminate the lines behind the alum side panels. Or, make a loop around the back of the radiater; that would keep it from getting dirt in it, in case you want to go racing in a coupkle of years.
