Factory, your Duster would have had a 22 inch in it with the lower outlet on the right. I have an aluminum radiator already with the tanks on the side.Its a cross flow. I didn't like the way it was mounted in the car when I bought it. It was mounted with some sort of clamping system that attached to the top and bottom. It looked like crap. If I use this radiator I'll weld a small piece of aluminum angle to each side, drill holes and mount it to the factory holes in the radiator support. Make it a much neater installation.
