Overhead photo of the Test-Mule Barracuda in the early stages of assembly (December 1967)
As you can see on the left side of this photo (passenger side inner fender-well), the frame area
below the shock tower was modified with a fabricated curve, to accept the 426 Hemi engine.
If you look closely, you can see that the passenger side shock-absorber was removed at the time of this photo.
