71-73 used a square upper reservoir behind
the seat.
68-70 were under the dash at the top of the kick panel.
74-79 were down by the front of the seat.
The 71-73 square ones are very robust. As
well as the plastic tubing. But the rubber sleeves are crap. They
are still available at the dealer or from Bus Depot [he probably
gets them from the dealer since his price and VW list price is the
same]
Part # for the sleeve is 211 611
833.
