Front sway bar bushings/joints.

[Jon Hall]

Ben,
Are you referring to the end links that bolt on the sway bar and
attaches to the control arm? If so... there are no aftermarket items I
am aware of.
If your referring to the sway bar bushings themselves... ES makes a set
and you can just pick up the phone and call Courtesy Nissan. The have
the set that includes the end links and sway bar body mounts.
Don't worry about the bar size.... that what the ES kit is made for.

I hope this helps you somehow.

Jon
