If you really want to know...
You have an RVR, right? When they converted it to left-hand drive, did they convert it to left-hand windshield wipers? If they did, find the original assembly, cut both assemblies down the middle, take both driver's side assemblies, then glue them together (you can use a fiberglass fill to cover the joint, then paint over it) and reinstall. The wiring and mounting? That's sissy stuff...

...You'll just have to find a way to synchronize the wipers to keep them from banging into each other... possibly by mounting one wiper a little higher... may work, may not... depends on the wiper geometries involved.
If it hasn't been converted... tough luck... you're going to have to find a surplus Mitsubishi Spacewagon front-cut and ask if you can buy the wiper assembly and plastic cowling that goes with it.
