Shock Recommendation

You wouldn't happen to know the part number for those Duster shocks would you? I can't seem to find Duster/Demon or Dart in their website
Here is the same part number Koni shock on my '65 Coronet. I don't think Koni knows that their shocks fit early B body cars either. Koni is a weird company that makes good shocks but they are too lazy to figure out what their shocks fit.
