Heater removal

["Ken Waringa" <kwaringa@dynsys.com>]

How do you get the stupid heater out of a 74 B?  I read the book, but it
still won't come out.  I removed the screw on the side holding it to the
fire wall and the screws across the front and side of the heater box.  I
have removed the defroster hoses.  It is loose, but won't lift out.  Does
the air flow cable have to be removed from inside the heater box before it
will lift out?  Something is definitely holding it from coming out, but I
just don't know what.  Any help will be appreciated.

Thanks,

Ken
