1992 Nissan Maxima GXE - How many o2 sensors?

[92Maxin]

My GF's dad is manager of a body shop so one of the Mech's gave my car a good look over before my inspection so i can fix anything first. Apparently the previous owner had some welding and such done to the exhaust before the main cat. We were only able to find 1 sensor right before it and he told me to double check to see exactly what might have been done. How many o2 sensors am i suppose to have and where are the locations so i can be sure? For quick reference the motor is a VG30E SOHC. Any help would be appreciated!!!EDIT: Never mind. Found what i was after at that "other" site. Guess they come in handy sometimes lol.

I'm going to move this so the Max guys can help you out.

Just one at the end of the y-pipe, before the cat, on the passenger's side.

yeah i wound up finding out. Thanks for the reply though! Trying to ge the car to pass inspection and finding little things here and there. Was checking outt he exhaust and the shop guy just wanted to be sure since we also noticed that im missing a number of bolts on the headers and where the "Y" pipe connects to it. gotta do that then replace the passenger side lower ball joint and im golden.
