Today's task was to test fit the seat box and floorboards. No problems, except to discover the handbrake lever will need to be adjusted as it is presently too low and strikes the bottom of the seat box opening.
Fuel tank is out at BGM Metalworks to have the intake tubes moved rearwards as much as possible. The central outriggers on the new chassis appear to be too far forward (by about 3/4 inch) and the fuel tank can't be moved rearwards enough to install correctly within the tub openings. I had already elongated the tub holes forward in an attempt to let the tank intake tubes pass upwards, but it wasn't enough - it would have required modifying the seat box as well, which I'm not willing to do.
Seatbox and floorboards are in primer only. Steering wheel isn't all the way on, as it was just being used to center the steering arms and test movement along the system.
