For my 1996. I need to buy a couple

 

Pre cat sensors?
1994-1997 oxygen sensor GM p/n 25312184
ACDelco #AFS75

 

Thanks man, wanna let me in on your source, I checked a couple of online etailers with no luck.

 

The Delco number you can find at ACDelco.com. The GM number I got from a parts cd I have. I already had it listed in with other part numbers on my web page. I think various other people have posted the p/n from time to time.

 

and the after cat o2 sensors for OBDII part# is 25312196
