Solved in way...
I found an old-timey brake line shop in Lacey, near Olympia, called ABS Brake Service (auto-start sound warning):

This shop is in the location that was my favorite VW shop/store Northwest Foreign Auto Parts and Repair before we lost the owner to the Big Casino a couple of years ago. Mark was super helpful and was always willing to get me parts for my Fiat/Bertone/Lancia when possible.
So the solution is I had 4 lines made, 3 for the pedal cluster to bulkhead and 1 to bypass the rear mounted front booster circuit, with appropriate ends, for $36.95 incl. tax. Hard to beat the price, speed and supporting local economy and all that.
Funny how almost every little thing on this Scorpion has led to another project and deeper exploration. While getting the cluster out I've learned a great deal about the system layout and also got some gauge cluster time in. Fresh bulbs and cleaning to ensure proper function.
I had "fixed" the car's previous problem by simply replacing the clutch slave cylinder. But, knowing these cars as I do, I decided to go ahead and replace the masters to prevent future breakdowns which are more inconvenient than planned work, even when it goes sideways. This led to the current SNAFU of stripped nuts and twisted line ends. This is what I should expect of getting into a system that is being serviced for the first or second time in 35 years. :nuts:
