Guys-- thanks for the input. I am looking for bodies that will be compatible with the Slottech c-6 magnet car for the new Spec stock class that HOPRA has just voted on. The rules for the body are stock with no cutting,grinding or drilling(basically stock). Minimum 3.5 gr. body weight. The G's have the gt 40 type around that weight. the Wizzards have the new wiz hardbody at about 3.7 gr. And the Slottech will take narrow chassis tyco bodies once the body posts are removed.
