I have an extra pair of Mazdaspeed adjustable Heim-type sway bar endlinks. They are good for all 4 corners on 90-05 NA and NB's, and front-only on 06+. If you are lowered or plan to adjust preload on your sways (or corner balance), these are great.
I got 4, but can only use 2.
$80 for the pair, NIB.
