I find that the original "twisted" angle of the accelerator pedal is correct for me.
I would prefer to have it duplicated from solid "billet" as the original does have the reputation of breaking easily, but honestly I can't see how that could happen anyway? You work the pedals in the Pantera by toe-tapping them. Not foot stomping on them like in your F150. The DT logo is kind of "Kool" to have as well. Attempting to reshape billet by bending it is not the most desirable approach.
I do know that I remade the "kick panel cover" against the tunnel out of .090" aluminum sheet metal. I believe the original molded plastic one has a molded in spacer on the back side of it. So I agree, that one can gain some space to move the pedal to the right.
I find that mounting the cable on the right side of the pedal works the best along with the original cable retaining bracket spot welded to the tunnel so I left that alone.
No one that I know of has compared variations in construction of early cars to later cars in this regard so I would not automatically presume that the factory made no changes in construction on later cars to gain more room for the feet.
Although my car is a'73, it is an early '73. Sometimes called a '72-1/2, built in September of '72, so it still has some early build features.
From what I know of US market Panteras, the '74 model year had the latest improvements which sometimes included very small, otherwise unnoticeable changes.
In any case, I am attempting to make this discussion helpful to Pantera owners who are less involved technically or less capable of initially recognizing that some issues are correctable and can make the car much more enjoyable to use with small changes.
@CTjackster. The wear pattern that your picture shows on the brake pedal, is the corner that you cut off, just like that pattern shows.
