I removed the stock pads from the pedals and then bolted the ACs to one side or the other of the stock arm. It helped in getting the pedal spacing where I wanted it.
On the other had a friend removed the entire boss off of the back of the ACs and then bolted the ACs to the stock pad.
Kind of an "I think I want to do it this way" option. We get the chance to decide a lot of those, don't we?
Good Luck
