No my buddy is not a sale men he has been working on cars for over 30 years.
I call the parts dep the part# for the LT1 is 16214671 and the LT4 is 16214681. they did not have one for the sensor BUT when I did the one on my car the # on the sensor that came off my car was different from the "LT4 " sensor I got.

i replaced both when i back-dated the computer to OBD1. i replaced the module first. then i noticed i was getting pretty bad knock so i replaced it and all is well.
