How to Read FoMoCo Part Numbers

(Note: This following information is primarily geared toward 1960's Fords, although it generally applies to later years as well.)

Ford part numbers (other than hardware parts) are coded in two basic ways:
Regular parts have a four character prefix (LFLL), a four or five digit part number, and a one-letter suffix.

Example: C5ZZ-5255-F (Exhaust "turn-down" tailpipe on '65-66 289 4V Non-GT Mustangs)
Many body-style specific interior and trim parts use seven digits in the part number, the first two of which identify the basic bodystyle application, with the last five identifying the specific part within a general body area. A three-letter suffix may be used, usually to indicate color.
Example: C6ZZ-6504290-BAB (Instrument Panel, 1966 Mustang, Black)

The following tables attempt to further elaborate on the coding of the various portions:


Prefix

DecadeYearModelDepartment
A = 1940's (often omitted)
B = 1950's
C = 1960's
D = 1970's
E = 1980's
F = 1990's
Last digit of year of introduction or revision
A = Ford (Generic) / Galaxie
C = Truck
D = Falcon
E = Explorer
F = Foreign / Trans Am Racing
G = Comet (Later Montego)
H = Holman/Moody HiPo Part
J = Industrial
L = ?
M = Mercury
N = ?
O = Fairlane (Later Torino)
P = Autolite (Later Motorcraft)
Q = ?
R = Rotunda (Generic)
S = Thunderbird
T = Truck
U = Econoline/Club Wagon Van
V = Lincoln
W = Cougar
Z = Mustang
A = Chassis
B = Body
D = ?
E = Engine
F = Engine Accessories
J = Autolite
M = Holman Moody
P = Auto Transmission
R = Manual Transmission
S = ?
U = ?
W = Axle
X = Muscle Car Parts
Y = Lincoln/Mercury Service Parts
Z = Service Parts
Note: For 1940's parts ("A") the first character is sometimes omitted. Similarly, the final character is occasionally dropped at the whim of the Ford Parts Number creators. Thus, such items as "Ford Rubber Cement" may appear with a part number of "8A-19552-B", rather than "A8AZ-19552-B"

Note: Subassembly parts or accessory kits may add an additional letter (starting with "A", then "B", and so on) following the Thousands digit in the part number identifier. Thus, we have a Mustang automatic transmission shift lever with part number "C5ZZ-7213-M", while the accompanying selector dial for a center-console equipped Mustang would be "C5ZZ-7A213-D".
