Outer Limits 4x4 Board

just after some thoughts on if i could put any misubishi aircon on her?

Hmmmmm don't know about any Mitsu a/c that could be used.
But definitely Paj or Triton would be the go if you can find the bits or a cheap wreck. You can use a Sanden compressor from a Sigma that bolts onto the standard 3.0V6 block bracket. You can get these for $20 at a pick a part

so a pajero v6 is the same as a triton?

Yes it is
