Absolutely not.  The parts are the same in their function but not even
close in their form.  The Vanagon heater boxes will only fit '80-'83
Vanagons and Bus heat exchangers will only fit Buses up to '78.  The
differences are in the shape of the exhaust ports in the cylinder heads
(Bus=round and Vanagon=square) and in the connection to the fan housing
(Vanagon=no connection while Bus has a connection) not to mention the
locations on the heat exchangers for fresh air intake.  There's no way
to use the '72-'74 Bus exchangers on a Vanagon.

Your best bet is a junkyard or try Jim Thompson at Old Volks Home.
