The stock throttle pedal location fore and aft is not real comfortable for a lot of drivers in an original Cobra.

I don't notice it hot footing around playing but if we have an hour a long road at a steady pace my right leg is not comfortable in the bend it must be in to keep steady unless I prop it against the transmission tunnel (which gets pretty warm). Adding washers to the stop to move it closer to the seat would be the wrong way to go for me for sure and I am 5'8" tall.

The only modification I have noticed on an original car is cut the bolt shorter, which I guess allowed the owner to reposition the pedal forward for right leg comfort.

My discussion for stock length stop is for undamaged significantly unmodified original cars. If the geometry of the car you have is different, including an original car with reproduction foot box or just mislocated foot box, the parts specifics Shelby American came up with for new Cobras five decades ago might not be right for your application. I have worked on original cars that have been crashed badly at some point in their past. It is real easy to find various features in the front cowl / dash/fire wall area ¼” inch to ½” inch or more away from where they would have been before the crash(es) and repair(s).
