NAPA? again lol... Or Summit racing, or Jegs, or Autozone! they ALL have em for the HO, thats for sure! as for the Renix, unless its a different story, they will have it for 19.99-24.99.
Ok update to my post, looks like 91 and up only is Listed. is there a difference? I dont recall. But Dorman / Help products has them available, so any parts store can get you the newer year and then maybe just compare? It looks like the price went up a bit too since I bought mine, 30-40$ looks like the current average.
