Punky, don't spend much time fooling with your stock 'dual-point' distributor. ALL internals for Ford distributors interchange back to about 1959 and at least as far forward as 1988. So rip the thing out the easiest way possible (the rubber o-ring is likely stuck to the block) and use virtually any wrecking yard dizzy body with all your existing parts. It's possible to tailor the centrifugal advance curve, adjust vacuum advance and even use a Ford-built big-cap adapter on those stock bodies. Electronic innards fit inside, too.
