Thread Size

I want to clean the threads on an original lock plate and the screws. What is the correct tap and die size for this. Any help would be appreciated?

Springfield used 8-26, 10-26 and 12-26 (Lock is #10 and tang screw is #12). The only place I know to get them for a reasonable price is http://www.trapdoorcollector.com/6-13Taps.html
