The 1989-1991 anti-sway bar
link is one piece but use spherical ball joints in the ends to minimize
binding. Due to it's plastic construction, these flex under load, which is
undesirable.  Under extreme conditions (like racing on a track), these
plastic end links can break due to the extreme loads put on them during
cornering.
