Does anyone have an opinion about installing new O2 Sensors in my 2000 A4

The front sensor is a piece of cake. The rear sensor...I don't know. I just ordered one on line about half an hour ago. I might try a doing this with a long extension from the top. I am not certain how to get to it from the bottom. The front sensor, which I replaced already, came out with little effort.
Either buy the O2 sensor wrenches or rent one for free at Autozone.
