i have a 13g off a 6th generation VR4 galant and i'm having a hell of a time finding fittings to go into the oil feed inlet and the water inlet/outlet. i'm going to get AN-barb or flare-barb fittings, but i've been to two plumbing/hose adapter stores and they are completely stumped on what fits. does anyone know the specifications or thread sizes to these inlets/outlet? again, the oil feed and water feed and return, thanks
