I have a Blackwatch "Street" swaybar for the Elise (3/4" diameter, the smaller one). It is in good shape, ~15k on the bar. Bushings look fine, endlinks are tight.
Bar is in Denver; shipping would be about $25 in the lower 48.
$200.
Pics tomorrow, but I figured I'd get the ad out - a pic of a used swaybar only tells you so much

. It is silver. It works great.
