The example I posted were all from the past. Even the Mallory built Mopar Performance distributors with their crappy YH advance mechanism haven't been made in at least a decade. Do you recall if you were you looking at a dual point - cast iron distributor? Or maybe just at the spring kit I posted? The long looped secondary spring is a key ingrediant in the (not) secret sauce the DC/MP was providing to racers and enthusiasts.
