Looking for an 8-AN fitting to tap my pan with. Where can I get one of these bad boys?

 

Summit Racing carries a full assortment of fittings from Earl's and Aeroquip. That should be what you're looking for. I only suggest them because they ship so fast if you're in a hurry and can't find it locally. I got some stuff from them, and the rest from a local speed shop. Everything I'm using was made by Earl's though so whoever carries them will have what you're looking for.
