Will OEM front brakes (rotor, caliper, bracket) from a 1999-2000 Civic Si fit a Honda Civic EK (1996-2000)?

Q: Will OEM front brakes (rotor, caliper, bracket) from a 1999-2000 Civic Si fit a Honda Civic EK (1996-2000)?

Unclear. Sources conflict on the part itself: Honda's 1999 press release gives the 1999 Si 10.7-inch front rotors, while a fan site lists the 99-00 Si with the 10.3-inch brakes and calls them a bolt-on. Knuckle compatibility on DX/LX cars was not confirmed by any source read. The fan site timed out on the calibration recheck; its claim rests on the earlier read.
