2007 Mitsubishi Montero Sport Diesel - Calipers

[LuckyEnough]

Woman in Need!!!! Does anyone know where I can find a US parts distributor that can find the correct caliper for the 2007 Montero Sport Turbo Diesel that was built for use in Central/Latin America? Have tried US dealerships and they don't even have (or won't spend the time) to reference the similar US/North America Mitsubishi vehicle that I could substitute the US part for the caliper I need on the Central American version.

Yes, I can likely buy it in Central America but it will cost an arm and a leg. Autos and parts are muy expensive! Was planning on taking the part back with me and an expat friend is going to do the brake job.

Any help is greatly appreciated!
