Skinned Knuckles is a monthly publication written by and for antique and classic automobile restorers. Fondly known to subscribers merely as "SK", it answers to either name. It has been in continuous publication since 1976. This journal promotes authentic restoration of cars and trucks. It does not advocate modification, alteration or ‘hot-rodding’. Its mission is to preserve the historical integrity of vehicles, ranging from the earliest electric, steam and internal combustion or gasoline engines to the period where legislation dictated emission controls and computers replaced the mechanical components of a car.
