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?

The RE is completely electronic controlled and the RH is road speed (governor) controlled shifting but the housings, output shafts, VB and OD section and controls can be swapped from one to the other as far as I know.
Of course the computer, VB and controls all have to go together.
On the 4x4 question, the OD section and output shaft with long housing from a 2 wheeler will swap over to the 4x4 trans.
And yes, with all the sensors from a 96 up a 95 down becomes an OBD capable setup.

I thought I mentioned it but I guess not, that I have the speed sensor for the RH housing sitting out in the shed and I don't need it since I am using an RH with pressure switches for automatic shifting and a standard speedo cable (well, a longer standard cable anyway)
