BODY CODE PLATE
DESCRIPTION
The Body Code Plate (Fig. 1) is located on the floor
pan under the passenger seat or attached to the front
face of the radiator closure panel. There are seven
lines of information on the body code plate. Lines 5,
6, and 7 are not used to define service information.
Information reads from left to right, starting with
line 4 in the center of the plate to line 1 at the bot-
tom of the plate.
The last code imprinted on a vehicle code plate will
be followed by the imprinted word END. When two
vehicle code plates are required, the last available
spaces on the first plate will be imprinted with the
letters CTD (for continued).
When a second vehicle code plate is necessary, the
first four spaces on each row will not be used because
of the plate overlap.

FASTENER IDENTIFICATION
DESCRIPTION
The SAE bolt strength grades range from grade 2
to grade 8. The higher the grade number, the greater
the bolt strength. Identification is determined by theline marks on the top of each bolt head. The actual
bolt strength grade corresponds to the number of line
marks plus 2. The most commonly used metric bolt
strength classes are 9.8 and 10.9. The metric
strength class identification number is imprinted on
the head of the bolt. The higher the class number,
the greater the bolt strength. Some metric nuts are
imprinted with a single-digit strength class on the
nut face. Refer to the Fastener Identification and
Fastener Strength Charts.

FASTENER USAGE
DESCRIPTION - FASTENER USAGE
WARNING: USE OF AN INCORRECT FASTENER
MAY RESULT IN COMPONENT DAMAGE OR PER-
SONAL INJURY.
Figure art, specifications and torque references in
this Service Manual are identified in metric and SAE
format.
During any maintenance or repair procedures, it is
important to salvage all fasteners (nuts, bolts, etc.)
for reassembly. If the fastener is not salvageable, a
fastener of equivalent specification must be used.
DESCRIPTION - THREADED HOLE REPAIR
Most stripped threaded holes can be repaired using
a Helicoilt. Follow the manufactures recommenda-
tions for application and repair procedures.
INTERNATIONAL VEHICLE
CONTROL & DISPLAY
SYMBOLS
DESCRIPTION - INTERNATIONAL SYMBOLS
The graphic symbols illustrated in the following
International Control and Display Symbols Chart are
used to identify various instrument controls. The
symbols correspond to the controls and displays that
are located on the instrument panel.
METRIC SYSTEM
DESCRIPTION - METRIC SYSTEM
The metric system is based on quantities of one,
ten, one hundred, one thousand and one million .
The following chart will assist in converting metric
units to equivalent English and SAE units, or vise
versa.
