    Added Notes:
    All Fox-Body cars are not the same.
    The numbers with length and location that I’ve provided above were for a 1989 GT with A/C, Power Steering, Stock Alternator, and the Air Pump in place.
    Bolt only for position #8 is correct for 1989. However bolt and stud combo is correct for 1990.
    At this time Totally Stainless latest catalog now shows the following part # for the long and short water pump bolts.http://www.totallystainless.com/
