Putting together a new system for my ‘16 Ram 2500. I’ve got the box in; fits good with a little carpet trimming. Seats do fold down but touch a bit towards the back of the seat. Has anyone made their own spacers, and if so, what’d you use? Ive seen cheap mdf board kits but I want something more solid. I’m sure I could just probably machine something myself. Any ways, tips anyone?
