I don't know what your problem is, but all the screw holes are the same size for O2 sensors. Toyota normally used a bolted on flange that the O2 screwed into.

I think he's saying the actual O2 sensor, not the screw holes, I've seen 2 different size O2 sensors off of the 7M motors. One might have been for the cressida, but I'm not sure.
