E4TZ-9A758-D in the listing is probably showing the engineering number
found on the part, not the part number you would order at the counter.
Because ALL gas pedals in "Ford speak" have a base part number of 9725.
E7TZ- was designed in or for 1987, and supersedes/replaces the earlier part. (R/B)
All you can order through the network now is the thinner E7 pedal.
