The reservoir is a bag type hanging over the side . You can see the hose attached to the cap of the bag and the two hooks that support the bag . Its a 65 thing , 66 used a plastic bottle on top and the pump mounted over the side .
What I know of 1965 was the first year for the plastic bottle mounted on the inner fender. The washer pump was mounted beside the shock bracket towards the engine. Did late 1964 assembled cars had foot pump or electric pump?
