After creating a reference datum jig I've been able to measure/cut/notch/clamp/tack-weld most of the new boat tail's space frame superstructure over two days.
It WILL require the pogo support as the swing mount experiences quite a torsion as the tail comes off the bumper perch,swinging into thin air.
This was anticipated,not a problem.
I'll work all weekend and by August 1st I should have a pretty good foundation for the finer dimensional work.
I'll have the Insight too,so I can really tear into the deeper projects.
