Those are points and condenser. Where are the Stinger guts? This does not compute. There should be a magnetic pick-up coil and a reluctor wheel under there. Was the Stinger even hooked up? Maybe it failed and someone back-fitted the points. The electronic ignitions back then had a lot of teething issues. Even the early GM HEI used to fail so much they advised keeping a new ignition module in the glove compartment. Much later they discovered that it was necessary to apply a schmear of dialectric grease under the module. That way it passed the heat to the heat sink base of the distributor and then it lasted a long time.
