Right -O’-Way (ROW) has released a drop-in wheelset for the Sunset GP7s and GP9s, allowing a modeler to convert their model to Proto48. The wheels are the correct size, 40 inches as per the prototype, and are intended to be a drop-in replacement for the factory wheels. The axles, gears, thrust washers, and bearings come directly from the same manufacturer that builds the models for Sunset. Contact Jay at ROW for pricing and more details.
