For my 95 T/A the O2 part number is 25312184. However when I punch that in to GM Parts Direct or GM Giant the number changes to 19178930. I even checked with my local dealer and the same happens for them. So I ordered one and the O2 looks completely different. Has the O2 design changed for our 1993-1997 F-Bodies?

 

The part number changed some time ago. Don't worry about it looking different. Looks change all the time. The function should be the same.
