This is how I remember it also.
As Brett mentioned you can definitely solder on the connectors to the O-2 sensors. I've had pretty good results with this.
One other thing to note is that the '96 DI's actually have a different connector from the '97 and later DI's. I'm pretty sure the sensors are the same but the connects are different. At least I've been able to swap the connectors and have them work. For the GEMS engines I'm not sure the connector swap is really worth it anymore. The last few O2 sensors I got were around $80 at Advance Auto parts for the correct ones.
Another thing to note is that the 14CUX trucks use different O2 sensors from the GEMS trucks. They use a 3 wire titania type O-2 sensor. While the GEMS use a 4 wire sensor (I'm not sure if the GEMS uses a zirconia or titania sensor however). So these are not interchangeable. There is a pretty cheap alternative for these sensors though. You can use the Bosch 13021 sensor. Which I believe is used in a mid to late '80 Sentra. Again this will require swapping connectors. I'm currently running two of these in my '95. I got them for around $40-$45 each, and they seem to be working well according to the Rover Gauge.
