Alright, got them installed. The footrest is the easiest, because you can take the whole footrest out of the car, and just screw the new one in on top of it. The gas pedal screws right into the existing pedal too, so it's pretty easy. It took me a bit longer to do the brake and clutch because the four holes in the new covers didn't exactly line up with the four holes in the pedal, so I had to use a drill to enlarge the holes a bit. Broke one drill bit in the process, but that's what I get for buying cheap tools. All hardware is included: 4 screws for the footrest, 2 screws for the gas pedal, 8 counter-sunk bolts and nuts for the brake and clutch pedal, and an allen-wrench for tightening the bolts.
I need to get another picture with better lighting so you can see the "Celica" emblem on the clutch and brake, but this will have to do for now.
