I think the FJ40 seat is one position only. I've been thinking about how to remedy this as well, and am thinking that four 1/2" steel spacers with holes drilled in them will solve the problem; stack two together to raise the back end 1", or if that's too tall use just one to raise it 1/2". I think the bolts back there are M12, so you'll have to pull them out and get some longer bolts at AAA Metric or your other friendly metric fastener distributor where JIS is available.
