Any Magnum 500's on a blue dart?

I got ahold of Stockton Wheels and they did make Magnum 500's in SBP up until 8 months ago but they haven't been able to source material so they aren't even taking orders for them so that's out the window. That leaves my options at Rallye's or Cragars and I'm leaning towards a set of Cragars. Thanks for the help guys.
