maybe its to identify the press that stamped out the cross members just in case there were any quality issues anyone have any other lettering on there beds? | | | | | Joined: May 2012 Posts: 574 'Bolter | | 'Bolter Joined: May 2012 Posts: 574 | i have it stamped on my truck frame right behind the cab, not to mention the various parts with the "s" stamped on them, ie. radiator cap, gas cap, etc. Indy
