It seems to me that the chrome peices being fairly long and heavy, and supported at the outboard end of 2 1/2" x 3/8" flat bar, are going to shake and vibrate like crazy. Someome on that "other" forum emailed me, and said that there is a spreader bar that fits between the outboard ends of the bumper supports (the peice in the very top picture that does NOT have the trailer hitch welded to it), and that it connects to the vertical chrome bolts at the inner ends of the "bumpers" to keep them from shaking. the person sent me a link to a photo, but the link doesn't work!!! Can anybody shed some light on this???
