are they bolted or welded that year? I know by 74, they are welded to the A-pillar, just curious ??
68 & 69 are bolt ons, everything after that was welded.
bolt on hinges were on the 1970 as well till around the first of December when they changed to weld on. Both my friends and my 70 Acadians have bolt on hinges built in October & November, My brothers 70 Acadian built Febuary has weld on
