At this point, the frame has been flipped upside-down to make it easier to mount the bellcrank onto the underside of the crossmember between the outer 'rail and the X-member. Chad designed the crank so the rod can be pulled from the tubing if it ever needs service, even after the mounting tabs are welded to the frame. He can add washers between the tubing and mounting tabs for adjustment. It's important that the crank is mounted at a 90-degree angle to the master cylinder, indicated here by the longest scribed line (arrow). The four short scribe lines (from lower left to upper right in the photo) designate the location of the clutch pedal rod, clutch master cylinder rod, brake master cylinder rod, and brake pedal rod.
