The original Duraspark didn't survive the shift from the original body style to the big Bronco body style AFAIK. Most original Duraspark owners have aready swapped back to points and condenser or gone with a new aftermarket electronic ignition setup. The original Duraspark ignition had no provision for correcting base timing which really got to be a problem as the engine aged and components began to wear.
But, don't take my word for it. My only experience with the Duraspark system has been to rip it out of my brother's '76 because the modules like to just up and quit for a few hours....or ten minutes...or three days....no rhyme or reason just whenever they feel they need a break.
