Man are you into a huge challenge!!! Been there, done that!!! That is probably the hardest swap you can do in a zuk! You need to make new holes in the tunnel for the shifter location, brake pedal swing assembly swap (switches needed), complete wiring and computer swap.....I said it was hard!
I did this and opposite conversions to a couple of kicks a couple of years ago.....you are better off going and buying an auto and swapping everything over and selling the manual!
