Mines got the same imprint, and the same flash. Just compared chassis, and the reveal just before the rear wheel wells is different on the two kits, as are the rear suspension mounts. The kick up at the front of the frame seems different too, the frame rails ahead of the grille shell are more curved on the original highboy version. But the real question is why would Revell tool up an all new kit? The differences are so subtle, no one would ever notice. Well, except for us!
