2nd won't engage?

Mac lists the 91A-7320 but he doesn't have stock.

(I think I remember who I got it from- another Barner. But, that was YEARS ago.)

Okay, you definitely have the later gears and syncros. I can see why it was not going into 2nd gear based on the position of the collar/sleeve. That's typically one of the reasons why the 68-7320 fork does not work even when the internal dimension of the fork is ground or reshaped to fit the later syncro 2nd/3rd gear collar.
I think your best bet would be find a complete and correct double detent '39 type shifter top with the 91A-7320 fork.
