Sitting in the car all suited up like you about to stage will determine peddle possision. Also , thinking out of the norm helps. Notice that on Roos peddle that the top curve goes back towards the driver? If you reverse that and go forward and offset the pad, you can gain some extra leg room or find a more favorable mount for the pivot. You will have to either make the peddle out of tubing or thicker plate (norm .250) because of the twist from the pad offset. I Frequently have to do that on some restos for the clutch peddle because the new owners are bigger than the original smaller drivers in a very restrictive space.
