Depends what parts you need, service items like filters and so on should not be a problem and you should be able to part number match to locally available parts, brake pads might be a little harder but if you are prepared to wait and can afford shipping costs everything you might need would be available on line.
Forums like IH8Mud in the US I believe would also be able to provide advice and you would certainly have a unique vehicle for the country location.
It looks like you have a interesting truck and probably some stories to go with it so if you plan to stick around please do take the time to introduce yourself in the
club house, oh and pictures are always something we like and we are a friendly bunch on here
