On my V-dub someone just bent the pedals. Didn’t do them any harm, it seems.
What’s the Chevette setup look like? Seems to me you could either bend the pedal stem or relocate the whole thing, including the master cylinder.
You might also consider the gas pedal and options for making it more compact. Original TDs had very small foot boxes, and the gas pedal was just a roller on the end of the linkage. Placed low near the floor, right next to the tunnel, it left enough room for most folks to discern the brake from the accelerator.
