This can won't fit on the driver's side of your truck out of the box, so it would need modifications to the mounting bracket and probably the hoses. The most effective way to adjust your can setup would be to get this can, use it on the passenger side, and then transfer over your current can to the driver's side and modify its lines to get it to work. If you don't want to go through that hassle, then grabbing a second inline can would be the easiest solution.
