fitting a OM617 turbo and transmission in to an right hand drive W140

[Rishiganasen]

greetings everyone i am planning to put an OM617
turbo and trans from a W126 into a RHD W140
280/320 and this are things that i would need info on.


1. would the this engine bolt up to the 140 chassis
with little to no mods?
2. how can i make the guages work with the
existing cluster to the 617. Examples
RPM,speedometer,fuel guage,oil
pressure,coolant temp
3. how can i make the ac work on this swap


i know 606,603 can be fitted but i cant seem to find
them readily only the 602 are able to be only found in
my region
