2nd gen Runner, SR5 truck, 60/40 split bench(non SR5X-cabs) will bolt up the easiest, Celica seats and MR2's work as well, if he is tall, MR2 seats will work the best as they have the thinnest backs. From there just about any Japanese seat will line up with the outer two mounts, the inner front mount usually has to be drilled, the inner rear often lines up with the seat belt mount, or you drill a hole(reinforce w/large washers). The only issue I have found with post 2000 Japanese seats is the height of the bottom cushion with the sedans.
