First, take out the drivers seat. It is so much easier this way. Next climb under the dash. Take out all the nuts that are attached to the pedel assembly. You will have to take the nuts off the brake booster they are attached to it. Take the nuts off the top of the assembly, about 4 i think.
Don't try to take the pedels out individually. I tryed for about a hour. It can't be done not enough room. Just take out each nut attaching the assembly to the brake booster and the few attached to the steering column and u are good to go. Takes about 10 mins at the most and a little bit of moving it just right to get it out. Take the gas pedel to it is skinnier than the auto pedel.
