    I just bought a $950 1999 Mustang. But of course it needs some fixin. Are all or most parts from 1999 to 2004 Mustangs interchangeable?

    Welcome! Most things are about the same from 99-04, some parts changed on the engine after 00-1/2, but most things are the same otherwise.

    99-04 is all New Edge. Everything will work between years, some with
    modifications. Late model '04s got the 3.9 V6, but it will still run in
    99-03. However, the new Edge basic proportions, interior design, and
    chassis remained the same as the previous model.

    A split port induction system was added in 1999 for 190HP

    1999–2000, while the Mustang GT's 4.6 L V8 saw an increase in output to 260HP
    due to a new head design.

    01-04's V6 HP was increased to 193 HP.

    The 3.9, on top of the 01-04 increases, is another +3 ft-lbs in torque, with
    Noise, Vibration & Harmonics improvements.

    The only major parts that differ are the pistons and engine bore, they made some changes and refactored 3.8 to 3.9, but all other parts interchange.
    It's a worthwhile project as these cars are getting scarce.
