The 1968 Shelby Interior Décor Group (sometimes called "Deluxe Interior") includes:
Woodgrain Dash applique, Deluxe door panels with simulated woodgrain, woodgrain door pulls,
chrome buttons in seat backrests,
bright pedal trim and a color coded automatic transmission shifter handle.
Shelby changed the automatic transmission shifter handle on later cars.
They also included the simulated, woodgrain steering wheel with a woodgrain center panel and a Shelby emblem.
Painted metal surfaces are Black Charcoal Metalic in color and include: Dashboard / A- Pillars (includes headliner bracket),
steering column, Interior door surfaces and the fold down seat trap door (both sides) for fastbacks.
The dash pad is black . The metal dash pad straps at the base of the windshield are black with texture.
The carpet is black. This includes the carpet on the side of the Shelby console which should match the floor carpeting.
The seats are either black vinyl (6A) or black comfortweave (5A). They have two chrome
rectangular buttons in the backrests. Black vinyl inserts are sometimes referred to as "kiwi". Comfortweave was not used on convertibles.
Soft Trim is black and includes: Door Panels / Arm Rests / Headliner / Steering Wheel Pad / Vinyl A-Pillars Pads (early) / Vinyl Lower Dash or Knee Pad (early)
The deluxe, door pulls are black molded rubber. The sunvisors are black on fastbacks and convertibles. The type of the material is different. Convertibles used a smooth style visor. Fastbacks used a moongrain material.
Steering Wheel / Deluxe Automatic transmission Shifter Handle / Console and pad: black Molded Plastic
The windlace is black.
The window crank knobs and are black molded rubber. The deluxe interior uses the shorter, window crank handle.
Rear Seat Area Interior panels (all cars) : Black Charcoal Metallic paint over fiberglass. The upper panels on the fastback are Black Charcoal Metallic paint on fiberglass or metal.
The strapping brackets are also Black Charcoal Metallic.
The seat belts are always black on a Shelby. They are the 1968, deluxe metal style.
The kick panels are black molded plastic. Steering columns were pre-built and often showed up on the production line in other standard
Mustang colors. Since most of the 1968 tilt columns were used on Shelbys, the color was often changed to match the Shelby's interior.
There were several cars built with a non-deluxe steering wheel. These cars were built during a very specific time period
of production. I have seen some early cars use a black automatic shifter handle.
The fastback trap door is Black Charcoal Metallic on the back side with a semi-gloss black hinge (non-metallic).
Here's a restoration tip. You don't want everything to look like you sprayed it on the same day. Try sourcing paints from different vendors for some parts.
These parts were painted an installed often times in different areas of the plant.
