- Channeled: Used mostly on '20s and '30s cars and trucks. A section of the floor of the vehicle is cut out on both sides of the cab/body and the body is dropped down over the frame rails. New floor sections are then welded in.
- Chopped: Generally refers to the top of a car or truck being lowered by taking a section out of the middle of the posts.
- Cowl: The part of a car/truck body between the front of the doors and the firewall. the windshield and front doors are mounted to the cowl. (crowel)
- Frame Swap: Removing the frame, suspension, wheels, tires, brakes and steering from under a car body and replacing it with components from another type or make of vehicle. Usually done with older bodies and newer chassis to get updated steering, brakes, etc. Possibly one of the most popular of these swaps is the '40s, early '50s Chevy pickup truck body with a later model Chevrolet S10 pickup chassis. In some cases, a builder will get lucky and find a chassis that very closely matches the original wheelbase. If that is not the case, then the frame rails will either need shortening or lengthening to more closely match the original truck wheelbase so that the wheels and tires look right in the wheelwells.
- French: Mount a component, such as a taillamp, into a panel rather than on a panel. Sometimes the lens is mounted flush with the surface with no trim ring or door (sometimes confused with tunneling).
- Front clip swap: Cutting off the frame of the recipient vehicle just ahead of the firewall and grafting on a frame clip from another vehicle.
- Sectioned: Involves taking a cut out of the middle of the car all the way around, then re-attaching the upper part to the lower part, making the body thinner in height. Sort of like turning the key on a can of sardines and taking the strip of metal out all the way around the can.
- Rear clip swap: Cutting off the frame of the recipient vehicle at some point on the rear portion of the frame and grafting on a frame clip from another vehicle.
- Rolled pan (roll pan): Usually refers to a fabricated lower panel at the front or rear of a car truck which is curved down and under rather like early rocker panels. They may be modified to hold a license plate or parking/back-up lights and sometimes even exhaust pipes.
- Tunneling: Sinking a component, such as tail lamps or radio antenna, below the surface of the panel, usually in a round tube. Rectangular headlamps or license plates are sunken in the same shape recesses (sometimes confused with Frenching).
