Ok, I got that info. and after searching, here's what I can come up with (from a friend in other forum) and think complete the info." I know the OBS up to Mar 97 build date have the sensor mounted above and behind the HPOP reservoir. Mar 97 to the end of 97 may mount in front of the reservoir (my 96 have it mounted behind the reservoir). Here's the part number info that goes with that (hopefully correct):
Exhaust Back Pressure Sensor Tube
(Ford) F4TZ-9D477-A, (International) 1821793C1 (94-Feb 97; mounts on bracket above/behind oil reservoir) (Dorman # 598-104) **
(Ford) F7TZ-9D477-AA, (International) 1830933C1 (Mar 97-end 97; may mount in front of reservoir)
There's another part number for the Super Duties (Ford 1C3Z-9D477-AA, IH 1837875C1)."
**the Dorman info was from another friend in another forum.
