According to Vans, the MK319-BS blind rivet is acceptable to replace and AN426AD3 rivet. In fact, according to the RV-6 manual, you can use these for the entire bottom wing skin (I wouldn't though). Vans doesn't use an AN470AD3 rivet anywhere.
EDIT: If you go to the Aircraft Spruce website, they list the ccc-32 as an interchange for MK319-BS, it isn't. The ccc-32 is a smaller diameter and doesn't pull well by comparison. Good for nutplates and stuff like that, but I wouldn't use it for a structual application.
