I have a 2.5" one, its an ebay one, never been used. I bought it to use on my turbo eclipse a while back but never needed it. I don't have a 240 yet but will have it soon.. let me know what you want to trade for it. I can get measurements when I get home (5:30pm-ish) and you could pick it up tonight if you want in Town n Country (Hillsborough near Vets expwy)
