it would be pretty cool to have a skeleton fabbed up that went frame rail to frame rail across the vx then extended out to become sliders.. that way any load on the sliders would be applied across the frame and not just on one side.. and you should be able to bolt it to the stock skid plate mounting holes so there would be no drilling or welding to the frame.. once you had that skeleton attached to the underside of your vx, then making plates to cover the area between that can be bolted to the skeleton should be somewhat easy?
