My Goblin is not built yet, but I did align and drilled the holes in the pedals to test fit them - they look like they belong there.
Be forewarned there are no instructions. I removed the rubber pads on the brake and clutch arms, eyeballed the new aluminum pads, marked for the holes and drilled. Note: finesse is needed to drill the plastic clutch arm to avoid the lever and have room to install washers and nuts on the backside. Some shiming under the new pads may be needed (the pedal faces are not flat).
The throttle pedal can be left as is, drilled and the new aluminum pad installed or the plastic pad could be removed and replaced with the new pad - would need a fabricated bracket.
