On the R33, and on this pic attached from the R34, you can see a grey rubber like material - this material allows a snug fit, without it the pedal is pretty loose on the metal.
Two bushes I got are the round one that sits in the bottom of the pedal and the clip-like bush that holds the top of the pedal.
Footrest, clutch, brake and the accelerator pedal are all in the car - looks like I won the race, pfffewww, it was a close run one
PS: total price for my full set was under $200, including parts, shipping, money transfer costs etc.
PS2: $169 for this group buy is in my opinion unbelievable price BTW.
