Richard,
Stronglight and TA provided different spindles for that purpose as well as others, e.g., triple configurations. It was expected the shop or user would know which one to use.

Ahoy ! Yes, a poorly written subject line. Let's see if I can raise it better. I'm puzzled by my lack of knowledge to fully understand the discussion.
In the recent spindle discussions, various spindle lengths were recommended based on taper standards (JIS, ISO, proprietary, etc...) and people's actual experience. There was no mention of bottom bracket shell widths (68 vs. 70) affecting spindle length.
When I recall the often Campag spindle discussions, 68 vs. 70 is a significant specification in those discussions, and, Campag spindles are marked accordingly.
Yet, in the current discussions of French focus on TA and Stronglight, the bb shell 68 vs 70 spec. did not come up. The discussion went directly to length without reference to bb shell width.
I've come away with the notion that as long as one has the correctly threaded cups, all TA and Stronglight spindles can be used in both 68 and 70 bb shells.
OK - Why? Why isn't bb shell width as important to TA & Stonglight spindles as for Campag spindles ?
Thanks.
