Flatbedbill, any chance you could post the pictures to this thread for all to see? I'm curious about your flatbed as well.
As far as the bumper goes, I don't think the stock bumper would work too well with a flat bed. It's going to look small compared to the size of the flatbed, especially if you're building it wider then the bed (and in turn the bumper). If you don't want to build a bumper, I'd say head to the JY and find a drop face bumper that's in decent shape and mount that up. I think my DMI would look great under a flatbed.
