How do I find out which Mazda 626's have compatible parts?

I drive a '99 Mazda 626. I need replacement power lock assemblies for both front doors. I would like to get them from an auto salvage but I need to know the range of 626 models that would be compatible. Does anyone know?|||drop by the mazda dealer go to the parts desk and ask them to help you on which model/years will work for you.. the people at parts counters are generally pretty helpful.,good luck.
