This set contains a pair of accurate resin mainwheel hubs designed to fit the Barracuda resin tires, for those not building the Tamiya P-51 kit. For modelers building a P-51A,B,C,D or K from Hasegawa, Trumpeter, Dragon, Hobbycraft or Monogram and using the Barracuda resin tires BR32029, BR32030, BR32031, BR32032. These hubs are not intended for the Tamiya kit, as the mounting to the gearleg is different.
