There Are Both Line Built And "after Market" In Those Years. You Could Add A Unit On Later. I Think They Bragged About Only Four Bolt Holes To Drill. The Rivet Deal Is A Good Indicator, As Already Said. Another Good Way Is That The Gvw Is About 600lbs More On Line Built. I.e. If You Have One And It Says 5000 Lbs On The Door Plate It's Not Line Built. If It Says 5600 Lbs It's Line Built (basic Number Will Vary Depending On Chassis Type)
