Just put the kids to bed, so I'm in the shop now.
To my knowledge, the pedal assembly is the same regardless if it's standard or HD. The differences are the spring and the bushings.
This spring set up is the standard unit (just like in your pics)...

And the bushings inside here will be plastic and smaller in diameter (I believe)...

What is the guy asking for his set? I'm just curious what you mean by an inflated price.
