Ford Part Numbers

By Rick Black

Many people see old tools with a FORD script on them and assume they're for a Model A or Model T. What I've found interesting is that few, if any, Model A tools had part numbers on them! Model T tools did, most of the time. And beginning in 1932, almost all Ford tools had a part number on them that also identifies the first year they were used. And the same numbering system is still used today.

Ford parts had a base number (like 17017) that identifies the part, a prefix that identifies the year (01A) and sometimes a suffix number that identifies revisions to the part.

Example: part A-17017-B

The table below shows a list of prefixes Ford uses in numbering parts:

Note: there were some variances, for example the V8-60 of 1937-1941 used a different prefix than the V8-85 models.

The "A" and "T" spark plug wrenches were nearly identical. Neither had part numbers. Most had Ford script. The basic difference is in the width of the open end and box end.
If the open end is more than 1", it's for a Model A.
If the open end is less than 1", it's for a Model T.


Modern Ford Part Numbers

The following is from" and was originally posted by Joshua Teixeira, then cleaned up by John Witherspoon.

Part Example: F4DZ-2B120A -- a RH brake caliper

F - means 1990 (E is 1980's, D is 1970's, C is 1960's, B is 1950's, A is 1940's)

4 - is the year within the decade that the part first was installed by Ford, so an F4 part was first used on 1994 model year cars

D - is the line of car :

  • A is full size Ford
  • B is Fairlane/Torino to 76, then 77-79 LTD II, then Festiva, then Aspire
  • C is Mercury Capri (60's - 70's), Escort
  • D is Maverick, Granada, Taurus, 96 and later Taurus/Sable common parts
  • E is Escort
  • F is common Tempo/Escort parts (same parts, different body panels)
  • G is Mercury Montego, Monarch
  • H is Ford heavy truck
  • J is marine (boat engines, stationary power plants)
  • K is Tracer
  • L is Lincoln Mark series and regular 4-door Lincoln
  • M is full size Mercury for unique parts (otherwise, use A)
  • N is Ford tractor
  • O is Mercury Montego, Sable, and Lincoln Continental
  • P is Bobcat and Pinto
  • R is Merkur, then Contour/Mystique
  • S is T-bird
  • T is light truck, Bronco, Explorer
  • U is Econoline can
  • V is Lincoln Town car
  • W is Cougar
  • X is Villager
  • Y is Lincoln or Mercury/Lincoln non-vehicle-specific part
  • Z is Mustang or Ford non-vehicle-specific part
  • 2 is Probe
  • 3 is Tempo
  • 4 is 96+ Sable body parts
  • 6 is Topaz
  • 7 is Ranger
  • 8 is Windstar
  • 9 is Aerostar

    -2B120 is the basic part number and identifies the caliper.
    If part of a pair, then the lower number is the right hand side (i.e. 2B120 is right, and 2B121 is left). The only exception is power window motors for only one car. Series means the 1000, 1001, .... 1999, 1A001, to 1Z999 where every basic part number is a unique part on a car, and the same part 'name' for a different car is differentiated by the prefix.

    Note that if your '96 car has a part number such as F4DZ-2B120A, then you know the part was first used on '94 cars, was installed on '95s and is still being used unchanged on '96s.

    Part numbers are not necessarily the same as casting numbers or the numbers on the part. Line numbers are different still.
