I'm looking to do this on my new (to me) '86 FJ60. Seatbeltplanet no longer offers rear 3-pt belts for 85-90 Cruisers. I'm going to assume this is due to liability, since we seem to know that 60's built after 1985 no longer have the threaded hole. I bet they don't want to sell the kit and trust shade tree mechanics like us to safely execute adding the nut in the "C" Pillar. Now, does anyone see why I couldn't order a set of belts for an '84, and put them in my '86? (After I add the nut of course)
