probably stating the obvious here, if you got a half cut then you'd get the ECU and the wiring loom etc. The manual ECU is, i beleive, different to the auto ECU, but will the transmission tunnel of your auto be ok with the manual? Do you need a different tail shaft/propeller shaft ?
You;d be able to sell off bits you didn't need to re-coup your cost.
I'm wondering tho would it be easier to import the full LC over? I mean youre going to have to change some things that you may not even thought of - like the fuel filler - do you have different nozzle sizes over there for diesel and petrol/gasoline ? Are the fuel tanks you have suitable for diesel? (i'm asking that one coz i dont know).
cheers
