This is assuming, of course, that there is a Vanagon engine in the
Vanagon. You never know nowadays (I came really close to buying an '81
with a '76 motor). Check the engine number; if it starts with a CV
then it is a Vanagon motor, or if it starts with a G it is a Bus
motor. If so, have you done your valves? :)

It is unlikely that the '72-'74 heater boxes will work regardless
(unless your motor is a '72-'74 built up to 2000cc with FI stuff on
it) but I would check the engine number to be sure what WILL fit.

My $0.02,
