Extremely Frustrated, Been Driving All Over Town
 

I am looking for a nut for my NTK o2 sensor that I got with my wideband. So far I went to ACE hardware, Home Depot, Menards and Autozone. No one had the right sized nut. anyone bought this nut before and know where I could get one?

Sorry, could someone put this in the third gen section?

This might be a good place for it.. looks to me like a good Kill by the company ya got it from :D
