How do you get the rotors off of a 1992 Buick roadmaster to get to the studs so you can replace them?

remove wheel. remove brake caliper. remove center "dustcap" from rotor. remove cotter pin. remove nut lock. remove adjuster nut. remove rotor. the rotor has the studs pressed into it so you now have 2 options. 1: press in new stud(s) 2: replace entire rotor.
