I took my 84 FJ60 to Classic Cruisers in Salida, CO to have rear seat belts put in. The replacements are three point belts from an FJ62. I also asked them to put in the rear seat back with head rests as well. I feel much better about my son riding in the back seat now. Stan at the shop did an excellent job, looks like it came from the factory!!!! He switched the seat covers around so everything would match (makes the wife happy). I paid more than I originally thought I would have to, but I think the peace of mind is well worth it.
