CAUTlOI$ Fasteners in subparagraph B are impor-
tant attaching parts in that they coo/d
affect the
perform>nce of vital components and systems, and-
/or
cou!d result in major repair expense.They must
be
repraced with one of the same part number, or
with an equivalent part if replacement becomes
necessa?y. Do not use a replacement part of lesser
quality
br substitute design. Torque values must be
used as
&ified during reassembly to assure proper
retention of these parts.
1. Plug antenna lead-in cable and power source to
radio. I
2. Put i&trument cluster in position and replace six
