[T2] Heater Boxes on '72 Riviera

[John Kolak]

Disconnect the heater boxes from the fan shroud, remove the fan and work
the shroud back a little so the heater boxes can clear the fan shroud when
coming down. Of course, first disconnect the heater ducting and alternator
bracket from the heater boxes. Originally there were also support brackets
that helped take the weight of the heater boxes off the exhaust studs, but
these are often long gone. Install them while you are at it.
