PARTS DATA

 


GROUPING
The Standard GM Grouping System has been used throughtout this catalog. All group numbers are shown in numerical sequence. Headings are listed in alphabetical order within each group.

PART NUMBERS
Right hand and left hand part numbers are often listed on one line, if the model application and description are identical. For example:

3.706  ―  SUPPORT, TAIL PIPE
1 399550 399551 1968-69 344 w/DUAL EXHAUST

In such cases, the first number on the line always refers to the right hand part and the other number refers to the left hand part.

SUPERCEDED NUMBERS
The number in brackets at the end of the description line (if included) refers to the old or superseded part. For example:

3.708  ―  U BOLT, TAIL PIPE and MUFFLER TO HANGER
AR 3719496 1966 ALL 6 CYL - INCLUDES CLAMP 1-7/8 IN   [SUP 381782]

The old and new numbers are not always fully interchangeable. Rework is sometimes required. Be sure to check model applications.

0.033  ―  BLOCK AND PISTON ASSEMBLY /WITH RINGS, CRANK AND CAM BEARINGS, LESS FLYWHEEL HOUSING/

1 X 325180 $ 1968-71 ALL 6 CYL - EXPORT ONLY  SUP 3930970

HOW TO FIND THE PART YOU NEED

 


For a quick way to locate the exact application of the part you are looking for, be sure to use the indexes and illustrations. They will be helpful in several ways:
  1. If you know the part name only refer to Alphabetic Index, note the group number, then go to that group in the data section.
  2. If you know the part number only refer to the Numerical Index, note the group, and go to that group in the data section.
  3. If you know the position only of the part on the vehicle refer to the Illustration Index for overall group, then to the illustrations in that group for a specific group number to turn to in the data section.
