I'm not so sure the indexing is critical. with the 13 teeth I think are on both drive and driven gear, the worst you could possibly
be off by is half a tooth or 1/26th of a circle or 13.8 degrees. Looks like there is enough room for adjustment to compensate and
put you back near the middle, or I have forgotten all about geometry.
