Diffuser Install Complete, Pedal Box Cover Installed

Tonight I finished attaching the diffuser to the frame. I slid the jack in under the diffuser and jacked the bottom of the diffuser up against the frame so I could drill a few holes and rivet it into place. The diffuser I have was quite a bit off in its design so the bottom of the diffuser does not sit flush to the frame. Not a big deal though, as I used the jack to push the end of it against the frame and sunk a handful of heavy duty 3/4″ long rivets into it to hold it into place. I pulled on it pretty hard to ensure it would hold up.

With the diffuser in place I installed the pedal box cover. This piece is not mentioned in the manual at all – it was just buried in within the aluminum parts. I don’t believe it was labeled in the parts list, either. This piece is meant to prevent water/air from getting into the driver footbox, but rather than silicone it in place I placed some double-sided tape under the panel edges to ‘seal’ it in case I ever need to remove it in the future.
