I know my 8" is from a '74 Maverick 'cause I saw the car it came from and I bought replacement (new) wheel cylinders and shoes from J.C. Whitney, but I am not sure how hard it will be to find such parts at other sources. 1974 does not seem that long ago to me but maybe the parts shelves start to clear out after 20 years or so?
