Will OEM 2000-01 S2000 (AP1) front stabilizer bar, 28.2 mm fit a Honda S2000 (AP2, 2004-2009)?

Q: Will OEM 2000-01 S2000 (AP1) front stabilizer bar, 28.2 mm fit a Honda S2000 (AP2, 2004-2009)?

Yes, reportedly. Yes, per owners: the 28.2 mm 2000-01 front bar mounts on an AP2, even with AP1 bushings. A thread lists 2004-06 bars as 26.5 mm front / 25.4 mm rear, so the AP1 bar is stiffer (Honda's October 2003 release also lists 26.5 mm front for 2003, so 28.2 mm is the 2000-02 bar); one reply cautions that mixing generations' parts changes the car's balance. Honda's 2008 releases list a 27.2 mm front bar for the 2008 S2000 and 28.6 mm for the CR, so do not assume the same difference on 2008-09 cars.
