I've been searching the forum and needed to know the hex size and thread pitch of the rear O2 sensor for a 1995 240SX. I do not have the OEM system on my car currently and I'm installing a universal aftermarket catalytic converter. I've already purchased the converter and will not pay more to get an "direct-fit" one. Thanks to anyone that can be of assistance in advance.
BTW, I believe it is a 12mm size but not for certain.
