AR5 will accept the TOD with minor grinding relief near the shifter housing. See the link above for details.
TOD works great with the AR5 and you get a better crawl ration because of the 1st gear being 3.95. I've since swapped my TOD out for a manual 2H, 4H, 4Lo TC but only because I want a larger crawl ratio.
As far as anyone who has driven the AR5/TOD combo we ALL agree Isuzu should have made them this way.
