• Most part numbers are made up of three parts.
• The prefix indicates the car model. (T= T-bird 1955-1957, B = Thunderbird 1958-1966, P = Ford Car 1954-1957, M = Mustang 1965-1973)
• The numeric base number, based on Ford's numbering system, denotes the particular part/component.
• The suffix, usually a letter or series of letters, separates the parts by the production years or other distinctions. For example part number 'T 6731A' is a T-Bird oil filter for 1955-56
• Although many parts are interchangeable, using the correct part number ensures that you receive the right parts for your car.

When entering part numbers please note:

• Part numbers have 1 or more underscores (_) separating the prefix from the base part number. Part numbers that have 4 or less numeric digits in the base number use 2 underscores and part numbers with 5 or more numeric digits in the base number only use 1. For example, part number 'T6731A' (oil filter) would be input as 'T__6731A', whereas part number 'T13106A' (floor mats) would be entered as 'T_13106A'. Part numbers that start with two or more letters such as upholstery items, 'TSC_57RDE' (seat covers), or accessories, 'TAC_07' (top hoist), use only 1 underscore.
