This setup is from Jason Paruta used to be a member here. You fab a bracket to accomodate the wilwood spot mechanical caliper and brake caliper. A You have to get two small heim joints with a threaded rod to attache the datsun handbrake cable to the spot caliper via a small home made bracket, riveted or screwed to the lower strut but it must be able to pivot.
Hope you get the idea, the picture shows everything.
Happy Easter,
