I built some roof jacks today. They are designed to be used in conjunction with a high cut on the column that the jack is attached to, and the next inner columns from the ones they’re attached to will have the reinforcement inserts attached to one side probably the lowers. Those will keep the whole roof centered during the lift and prevent it from paralleling sideways.
They’re made to attach to the two bolts on the rib at the top, and a middle bolt lower on the rib.
Slight modification, because that first idea was sort of half baked.
Bus structure recalibration modules mostly installed. I just need to verify they’re set in the right starting point to give me enough lift.
