just wondering if the rear brake swap from a 99-00 Civic SI is the same as the rear brakes on a 94-01 Integra??

i need to replace the rear right trailing arm (99 Teg) and was considering picking up a 99-00 Si arm assembly. i just don't know if it's the same thing. i want to use only the trailing arm w/hub from the Si, not the entire brake setup including the caliper and rotor.

TIA for any input on this!
