I just purchased a set off ebay (looks like the one below) and couldn't figure out how to install the foot rest piece. It comes with screws and nuts.
With the gas/brake pedals you just drill out holes for the screws and tight with nuts.
but for the foot rest area there is no access to put the nuts on the screw.
I don't understand WHY this truck doesn't come with a foot rest, even a Honda civic has one. Now that area is all dirty with the rain in the past few weeks.
