I know Kurt Williams with Cruiser Outfitters is capable of getting Montero Part from ARB. He is located out of Salt Lake and he is the best. Everyone loves Kurt because he runs a great business. Personally I would go with Kurt. He sells a lot of ARB parts. I know his site list just Toyota parts, but he can get his hands on anything ARB, OME etc. He just lists the Toyota parts because those are the ones he has in stock. It should only take him a few days to get the Montero parts.
