I'm looking for a Defender 130 a/c evaporator assembly core & case. I want to install an a/c system, it is a RHD.

I can do the compressor & condenser etc. on my own, aftermarket but i need help on finding a new a/c evaporator assy. I don't even know what it looks like. If anybody has a/c installed PLEASE supply a pic of the evaporator setup. I'm from Trinidad so it's easier for me to import from the USA but i'm willing to import from anywhere. PLEASE HELP.
