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.

DIGITS 14 THROUGH 16 Tailgate code • MWD = Plain Tailgate • MPB = Tailgate Applique (Black) 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 the line 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. BR/BE INTRODUCTION 3 BODY CODE PLATE (Continued)

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.
