You'll need an open ended wrench or an O2 sensor socket. It's right on the exhaust manifold. If you look down, between the radiator fans and the engine block, it's right there sticking out.

It's in the downpipe, shown as #27, pretty much where it joins from 2 into 1 pipe. Later years it's up in the manifold.

I never had a 91, but I guess it would be easier from underneath.
