yes you could. 98-02 f body brakes are what is used. you need to get a metal sleeve to center the f body caliper bracket bolts, or drill and tap the w body bolts to fit the f body brackets.

the w body bolts are larger. any time you go from a single piston to a dual piston and a inch or so larger rotor braking will improve.

it was one of the first things i did to my car after the second set of stock crap wore out in no time.
