Does anyone know where i could get hold of a front brake caliper for a k reg 1993 honda beat?

i have tried all the usual places including honda direct, does anyone know of an old honda beat that may have this as a spare part or i could use a caliper that may suit but is not a honda original, as you can tell im not a mechanic just passionate about my car, ive had it since new, and its immaculate but i reckon this may be a job that will need doing so im thinking ahead as the car has been discontinued and parts from honda are either no longer available or silly money, hope someone can help
