what type of rear o2 sensor does the 96 trans am have? I would go look but its like 25 miles away at my step dads place in the garage. I figured maybe I could save myself some gas if one of yall knew...I have searched everywhere....

there is a chart near the bottom...thats what im talking about

 

I believe they are the same ones that are in the front. I am not 100% sure tho.

 

no...the front is a rectangle type...the rear is one of the square types.
