Success!!!
Bought the 90 degree 3/8 flare off Amazon
https://www.amazon.com/dp/B01BYLUEZ4
(as I wanted to keep it all as low profile as possible, to be able to fit into a somewhat smaller storage bin)
The guy at a great nearby (small) hardware store (that sells all sorts of propane adaptors) yelled
"no one makes a 90 degree 3/8" flare! No one makes it!!!" when i mentioned it....
Then I showed him the one I bought off Amazon and he looked stunned.
Then I bought from him the adaptors to get down to my Camco Quick Connect male

- that'll go into my Camco 10' extension hose,

that will go into my propane Quick Connect Y (thanks
Greg A for finding this, and for the link!!!)

(so we can also have the Campfire In A Can going as well, while cooking a late dinner)
and that QC 'y' will go right into my (optional) QC on our forthcoming Escape.
Anyway now all I need is the right size of bin from Home Depot. For travel.
Thanks everyone for all the great help.
