Down below would have been front/bottom, rear bottom. I know technically incorrect but had they not come off would have worked.

Bank #1 is always the bank with the number 1 cylinder in it. The sensors in front or upstream of the converter are labeled #1 & the rears or downstream are number 2. So the sensor of bank #1, sensor #1 would be the front sensor next to the head. Based on what you said & how I interpreted your locations you have the bank #2, #1 sensor. So a similar sensor should be the upstream #1 bank sensor & the other two should both be downstream sensors.
