Wow Al, you're really having a time with this aren't you? Lesson for all the folks wanting to change pipes out there, check the bung hole!
This whole thing would have been a lot easier if I hadn't been told the probes have to be quite a ways in the pipe, and had I known the adapters would have been ok in the first place.
I used to call this kind of stuff all part of the learning curve, now it's just a pain in the backside.
Going well, nap taken and back at it, both sensors in and now I need to install the seat and coils and try to figure how to delete fault codes to start over again.
