Rear 02 sensor on 2002 2.4l

Does anyone know if there's a replacement or compatible rear O2 sensor that uses a standard m18 x 1.5 bung. I welded up a 2.5" exhaust for my truck and I was hoping there was something I could use that didn't require the 2 bolt flange.

 

I have seen them around you just need to look.

I found the 2 stud bungs easy to find so I never really looked for the threaded style.

 

I've searched a bit and think I'm just gonna pick up a narrow band 4 wire denso with the right plug and see what happens, just wondered if anyone already did this and had a known good part to start with. I currently have the original sensor plugged in and tied off to the frame but I'm still getting P0136: O2 sensor Circuit Bank 1 sensor 2.
