o2 sensors

So I plan on replacing my o2 sensors. I know it has 3 but I can't find information that says if they all 3 of them are the same part number. Any info on this would be greatly appreciated.

You could have 3 or 4 O2 sensors. They could be all the same, but I really don't know because you never mentioned the year of the vehicle!
So for us its a guessing game.

Yes a year would be helpful wouldn't it. I have a 99 blazer 4dr, 4wd, 4.3l v6. I've been able to find the information that says that there are 3 but are they all the same?
