I just received my rock sliders for my 2 door; but it shipped with the hardware for the 4 door. When I emailed RCI they told me they don't have the 2 door hardware from their supplier and that I should just use the parts from the 4 door, and toss what is left over. However it's not that simple...
Jim, I'm in the same boat as you, not wanting to replace my modular bumper, and also came across the Rough Country High Winch Mount. I also found a camera relocation kit that works with it: https://mountains2metal.com/BR6FCRL/
I look forward to know how you install goes...
