If you care to do it, just buy the new pedal for $30...and install it yourself.
Takes about 5 minutes with a 10mm socket and one clip.
i should do that and the mount the old one on the passenger side for those rare moments when my wife is driving and im riding shotgun...need a brake pedal and steering wheel too though....I actually like the new pedal better then my UN-shimmed original one.
The shape is better for my foot, and it's smoother.
I have the original one sitting right here for posterity.
