AU series 1.5 Smartsheild update drive line into Series 2 ute

[street beast]

Hi guys, did a little research on this but didnt really find what i was looking for so figured id ask here,

i have a 2000 Series 2 AU falcon ute factroy 5L v8 auto, engines getting a little tired, so i picked up a Sep 99 series 1.5 AU xr8 sedan thats manual, without doing as much research as i should have.

now my question is snice the sedan has smart sheild, would i get away with swapping the manual Ecu BCM and ing into my series 2 and all be hunky dory or is it going to be a pain,

one final question is tailshaft is the ute auto tail shaft the same length as manual? cheers

conversion done, Tried it with the ECU,BCM, and colum out of the 1.5, no go, used the 1.5 engine ecu, series 2 bcm and collum with a pats relearn and all is sweet. utes up and running again. and the manual tailshaft was shorter
