For a '79 FJ40 that came with power steering, are you referring to the power steering pump bracket or
the power steering box bracket.
JTO has brackets for a mini truck power steering conversion. If that's your aim, you're far better off contacting mud vendor Georg (orangefj45) for his brackets. You'll need to get a mini truck power steering box from a non-ifs truck and a saginaw pump. Search mud for the many quality threads on this type conversion if that is what you have in mind. Parts for this will be far easier to source than trying to install post '79 FJ40 power steering components. You will not be able to mount a stock post 79 power steering pump on an earlier block, as there are no holes drilled in the block. Drilling them in a pre '79 yourself is way past precarious.
