Yes, I am keeping the sensor....I am just wondering whether or not to order the cat with the sensor bung (if I know it fits). So if it doesn't fit, I will order it w/o the bung and weld in a bung myself. That is my question, whether all o2 sensors use the same size threeds or if they are different.
