While it's true that Ford didn't put matching serial numbers on major drivetrain parts like some other manufacturers... there are specific casting numbers on many of those parts, along with date codes. These numbers and codes do allow you to determine the year the part was (first) used and in most/some cases, the date the part was made.
With the date code from the ID plate of the car, if the casting and date codes of the misc cast parts fall within a period of 30 to 60 days before the car was built, and the part was originally available on that model, those parts are generally considered to be 'matching'.
Also... most serial number/data plates have code letters & numbers for the 'as built' options in the drivetrain in addition to exterior & interior colors and maybe some other options.
If the car and it's driveline parts, options, etc. appear as listed on it's data plate the car can be said to be 'numbers matching'.
Here are several links to help determine what may be 'matching'. Most apply to the late 50's cars (found them in relation to the car I'm working on) but if you need info about newer/other cars just do an internet search for it.
