I was looking for a rear sway bar bushing bracket for a while, ended up just buying one from a dealer. Wasn't too expensive. The lateral links are the same as all other 3rd gen Proteges.
I was told from the dealer $35 each for the brackets. I was looking online for the links and got on the mazda site put in vin and was shown different part #'s for the link, but you say they are the same.
