Friends:
I'm resurrecting this post from last year for anyone who wants to make the second row seats of their H2 recline. Our family has been using this hardware for about 11 months now and it has never malfunctioned. It lets the second row seats tilt back until they touch the bins in the cargo area -- -- you need an outside tire mount to tilt the right rear seat; you need to relocate the jack to tilt the left rear seat.
I'm 100% satisfied with the kit and if I had it to do over again, I'd buy it in a New York minute. The quality is very good and the reclining brackets are much stronger than the original GM brackets.
You order them directly from Japan via the attached link:
