46RE transmission without speed sensor

Looking at a different truck now, its a 4x4 so I would need to convert it over. I already have a 95 enigne and 46RH transmission. Could I use the overdrive/tail shaft off the RH to convert the RE over to 2wd or are they different?

Also, along these lines can I get all the sensors and wires off a 96 up truck and put them on my 95 motor and convert it over to OBD2?
