Ford Part Numbers

Ford part numbers were interesting in that they had a base number (like 17017) that identified the part, a prefix that identifies the year (01A) and sometimes a suffix number that identified revisions to the part. e.g. A-17017-B was used 1928-1931. Here is a list of prefixes Ford used in part numbers: T = to 1927 A = 1928-1931 B = 1932 (4 cylinder) 18 = 1932-1933 (8 cylinder) 40 = 1933-1934 18 = 1932 40 = 1933 48 = 1935 68 = 1936 78 = 1937 81A = 1938 91A = 1939 01A = 1940 11A = 1941 21A = 1942 69A = 1946 79A = 1947 89A = 1948 etc. 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 www.shotimes.com: Originally posted Joshua Teixeira, 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/Mystyque 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. Part Groups 01000-02000 series are wheels and brakes 03000 series are front suspension and steering 04000 series are rear axle and drive axle 05000 series are frames front stabilizer and rear suspension 06000 series are engine parts 07000 series are MTX transmission and clutch, A7000 series are ATX transmission 08000 series are cooling and grille 09000 series are fuel 09500 series are carburator 10300 series and up are generator, alternator, starter, distributor 13000 series and up are lamps, wiring, and electrical except for 10300 series 16000 series and up are fenders and hood 17000 series and up are speedometer and associated parts 17500 series and up are bumpers, jack, mirrors, washer/wipers, speedo cables 18000 series and up are air conditioning, heaters and radios 00000 series are body front (door posts and ahead and floor pans) including instrument panel and dash, but not gauges 23000 series and up are body sheet metal and exterior rubber bits 40000 series and up are back half of the car (trunk, roof racks, T-roof etc) 50000 series and up are exterior mouldings, emblems, and nameplates 60000 series and up are seats 70000 series and up are doors, windows, (not windshield), seat trim/covers Japanese weird parts use 2-piece Mazda part numbers 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 #'s are not necessarily the same as casting #'s or the numbers on the part. Line numbers are different still.
