I just found out yesterday that the rear O2 sensor on a Fed. Spec. 99 is a different part number than the rear O2 sensor on a 97.

Anyone know what the difference is? I know the 99 is cheaper . However, I was planning on putting the stock b-pipe from my 99 onto my 97, and if the 97's sensor won't fit in the hole, the the car would have one hell of an exhaust leak.

Anyone know the difference? Can a 99 sensor be used on a 97?

I think I've answered my own question...

Cattman and Stillen sell the same pipes for a 97 as a Fed Spec 99...so I can assume that the sensors will fit in the holes on the pipes.
