Yup another "my uncle worked at the factory" guy! That makes his uncle a configuration expert on every car built there, except his uncle cleaned conveyor belts! Have never seen the pinch clamps except on the power steering return line. Although I threw away all my emission stuff a long time ago. The types were the tower type, as shown on the air tubes on my (81 Vette), the wire type on radiator hoses, band on heater hoses. spring action on fuel. I've replaced some band clamp with the newer style Chrysler tension clamps but have gone back to the screw type where needed. Hope this lends to the general cornfusion on the matter since my SS is basically the same as BOP. 🙂
