Oxygen sensor question - 1996 Dodge Ram

From : john

Q: i have a 96 dodge ram 5.9l 360 with 120000 miles. it has original 2-1 exhaust. my check engine light has been on for a long time and the computer says its my o2 sensors. shopping online one place tells me i have 3 o2 sensors one in left manifold before catalyst one in right manifold before catalyst and one downstream. other places only list two. under the truck i find one o2 sensor that screws into the catalyst itself and one downstream before the muffler. i do not mind any more o2 sensors. they are both 4 wire just like the places that list 2 show. also does anyone have a place they have used before for buying o2 sensors there are a couple that all charge about the same thing but im always looking for the best deal. thanks for any help! .
