Build No. 01 of 04 Broken Arrow, Okla. Vol. XVI
The Broken Arrow Fastback

1968 Mustang Fastback

Nineteen sixty-eight sheet metal, taken to bare steel and put back together around a modern engine — so it can be driven the way it looks like it should be.

On the road at last light. The candy red goes almost black in shadow and lights up like a coal where the sun catches it.

Unique Customs — road test

The car arrived as most of them do — sound enough to move under its own power, and wrong in every way that matters. Floors patched over rust. A tired small block. Paint that had been laid over paint that had been laid over filler. The decision, made early and never revisited, was to stop trying to save any of it.

What came back is not a restoration in the concours sense. The proportions are correct and the trim is right, but underneath there is a modern engine, a five-speed, brakes that work in traffic, and suspension that will hold a line. It is a car built to be used, finished to a standard that makes using it feel slightly reckless.

“We stopped trying to save any of it and took the whole thing back to bare steel.”

The work

Stripping a car to bare metal is the only honest way to find out what you have. Here that meant new floor pans, new torque boxes, and a rear valance that had been filled rather than replaced. The engine bay was smoothed and the wiring routed out of sight before the Coyote went in — fitting a modern four-cam V8 between shock towers designed for a pushrod small block eats two weeks and shows up nowhere in the photographs.

Paint went on over a body blocked flat three separate times. Candy finishes are unforgiving — every wave in the panel is a wave in the reflection, and there is no hiding it under a heavy clear. The doors, hood and trunk were hung, aligned, removed for paint, and hung again.

The interior was trimmed to look period-correct at a glance and considerably better than period on inspection — the gauge cluster is the original housing with modern internals. Finished, road-tested over several hundred miles, corrected, and delivered. The owner drives it. That is the only outcome the shop counts.
