I got an extra of JBA LT's for a great price but the 02 threads are completely striped. I need to tap them!!
Any one know off hand what the thread size I need to tap are for the 02 sensors?

Nightowl answered this for the OEM manifolds, but since the same sensors can go in the same hole it should be the same tap. M18x1.5 tap

If the threads in the headers are stripped then there may not be enough material to hold the sensor once you've cleaned up (or re-tapped) the threads. A new bung may be required.

Check with a custom muffler shop. From what I've been told, bungs are a common size.
