Ford part identification numbers are separated into three groups by hyphens: the prefix, part number and suffix. The first set tells the model and year of the car, with the second set specifying vehicle body type and part location, and the part version is last.
The first two characters of the prefix give the decade and year, with the second two representing the car line that first used the part. The part number is typically seven digits, with the first two representing the body style, such as two-door or four-door. The third digit is the area of the vehicle, and the last four digits correspond to the part. The suffix is alphabetic, with the letter "A" representing the first version of the part, and subsequent letters signifying revisions or redesigns.
