Custom 1966 Mustang Fastback – Restomod Build

This stunning yellow 1966 Mustang Fastback has undergone a complete ground-up rotisserie restoration with extensive custom modifications and modern performance upgrades. The suspension features independent rack-and-pinion steering with front coilovers and a fully adjustable 4-link rear suspension for improved handling.

The engine bay has been cleaned up with shaved shock towers, smoothed inner panels, and hidden engine wiring. Power comes from a 302 V8 with dual cold air intakes, backed by a modern T-5 transmission.

The custom interior features a smoothed and modified dashboard, custom billet aluminum gauge cluster, modern air conditioning, and leather upholstery. This Mustang perfectly blends classic styling with modern performance, comfort, and custom craftsmanship.

Here's a shot of the 1966 Fastback before we began the build.

This is the first mock up of the Heidts rear 4 link kit.

All the windows in the Fastback have been smoked from the factory to compliment the overall look of the vehicle.

Another shot of the engine compartment showing the cold air intakes.

Another shot of the subframes and rear end.

Here is a shot when the Mustang was on the rotisserie. You can see the complete subframe under the floor pan.

Here is a straight-on shot of the custom gauges. You won't see any other Mustang with this type of dash and gauge set-up.

Here's the 4 Link after it has been painted finalized.

Lower side scoops. We molded them to the quarter panel for more of a seamless look. We also installed custom black grills in the front openings for a nice clean look.

Since the cap is now gone from the tail panel. We decided to black out the panel for a more agressive look. We also went with the Scott Drake billet aluminum tail light bezels for a nice finishing touch.

The original upper vent grilles were used. They were meticulously cleaned and restored to look as close to new as possible.

We decided to do something a little different with the gas cap. So we located it up on the rear quarter. We like the looks of the 1971 Mach 1 cap so that's what we decided to go with. Then, we recessed it so it would flow well with the body panel.

We had completely customized the dash on this 'Stang. We built the dash around this beautiful custom billet aluminum gauge cluster from Classic Instruments.

We installed the subframe connectors and chassis stiffener kit. This provides strength for the unibody of the Mustang by connecting the front and rear frame rails where they stop at the front and back of the floor pan.

We opted for the billet aluminum coil overs on the rear 4 link from Heidts. They provide 10-way adjustable rebound and dampening. They also have an adjustable collar for spring tension and ride height.

We the shaved the original shock towers, welded custom ribbed panels flush with the original inner engine panels and painted the engine compartment yellow to match the exterior.

We used a 302 engine with a modern T-5 manual transmission. We installed a dual a-arm independent front suspension with modern rack and pinion steering and disc brakes. To finish off the 302 engine we installed a polished dual cold air intake system.
