Is it 170mm arm length, as if prefer to maximize the mechanical advantage on the single speed?
Is the pedal threading the same as I haven't procured pedals yet?
If you use the inner ring position, the chainline should be pretty good. And 170mm is just fine.
As for pedal threads, they were available in French and standard threading, I believe. You can read more about it here

Are the derailleurs and shifters Simplex? If the shifters happen to be of the Retrofriction variety I, and many other vintage enthusiasts, would gladly take those off your hands.
