September_Squall, you scored a bargain there! Must remember to advertise here again in the future.. it works.
Oh.. if you need a bung to fit a screw-in type O2 sensor into a toyota header, this guy sells them for $8 or $12 depending on steel type. http://www.wtfauto.com . I spoke to Tristan, very helpful and professional. And man does he know a stack about MR2s.
