Correct distributor on 70 300 Hurst

Does anyone here know what the correct distributor would be for the 300 Hurst? I'm putting the finishing touches on my engine for my restoration and I'm not sure if my distributor is original or not (no tag). I know the 6 pack cars came with dual points, but I would presume the HP engine would have just came with the single point ignition.
