This is a resin cast Drag Racing chassis for the Revell 1/25  68-69 Dodge Dart  kits. It has larger rear wheel wells to allow for a larger tire. Keep in mind you will have to do modification to the kits interior tub to fit the larger wheel tubs. This part is geared to the more advanced modeler. Check out some other resin items at my ebay store Jerry's House of Resin. Bodys and model in pictures NOT included. And remember all cars should have FAT REAR tires.
