I'm assuming it is a manufacturers stamp. | | | | | Joined: May 2012 Posts: 256 'Bolter | | 'Bolter Joined: May 2012 Posts: 256 | Yeah I have wondered the same here...

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
