Thanks for all the replies :-)
Luke72 the parts that are left in my car also don't look very similar to what is in the diagram, the main part I am after is the heater core the rest can be made reasonably easily or adapted to fit. My car was converted from left hand drive to right hand drive when it was in Singapore, and they have made a few modifications them selves. There appears to be a bar that runs from the front of the bay to the back that they have cut out. I will try and get a picture to show what I mean.
Jalpa_Mike, I will put those guys on file I imageine I can probably source the cables locally but If I was able to get some out of a Urraco or Jalpa it may have been easier to get all the parts together :-)
Rovingtravler thanks for the heads up, I will send them an email and see if they still have the heater core available.

Thanks

Mike Hill
