yea o2 sensors are required importantly. you would want to find a forum for the disco to see what you need doing , it all depends on how the ecu used the information from the o2 sensor . otherwise it could be gussling fuel like nothing with no lambda sonds and not knowing what to do injecting just max fuel all the time.

Definitely need to re-use the O2 sensors either at the same location or further towards the engine if you have to.

Are you sure they are o2 sensors! most older stuff has the o2 sensor up on the headers and a separate temp sensor for the cats right by or in the cat. newer stuff requires the temp sensor in the cat, older stuff doesnt.
