I assume that these are a direct bolt on in US FJ60s? Shipping may make these cost-prohibitive, though.
Used to have a 61 and a 60. These split seats are the bees knees. Hauling and fitting items and people was far easier. As soon as I went to the 70 series and noticed my rear bench I quickly sourced some split seats like my old 61 split ones because I found they made my rear cargo space much more useful.
