Prototyping time!
What if I use ton frisket film to capture shape?

Or how about jamming some Silly Putty in there?

Haha, putty wrapped behind the gas pedal!
Not the best for this situation, but worth a try!
... and besides the fact that it doesn't easily distort after the fact, the film should do the trick!
I can draw on it, and it is low tack sticky for placing on my tread plate brass.
