The rear shoulder belt project is one i actually did get around to doing. Do you have the threaded bolt in the C pillar? I didnt and it was an ordeal to get the threaded plate back there but once i got it figured out it went really easy. I was able to get the trim from a fj62 and everything tomake it all look nice
man Ive been looking for a fj62 rear bench with headrests for like 2 years now. the ones i have found people want an arm and a leg for unfortunately. The Headrest seats also have a spot for the child seat anchor on the back of them too
