Here was my inexpensive solution that blends into stock interior rather than $pend on a fancy aluminum set...
Use another stock pedal and trim off the "hinge".
Next layer up some thin black ABS sheeting from Home Depot or your other local hardware to get optimum height with brake depressed.
Finally drill some holes, Counter drill the back of the stock pedal and bolt together using countersunk black oxide coated allen bolts and Nylock nuts.
Heel and Toeing has never been easier!
Have fun with your project!
