Power steering pump pulley wheel

[mopar4]

I'm putting power steering on my '81 BJ42 (RHD) so I got the power steering setup from a '92 Toyota Hilux that was at the wreckers. The pulley wheel on the power steering pump is bent and needs to be replaced. Anyone know what other Toyota has the same power steering pump or wheel as the Hilux? The 4Runner's is almost the same diameter, but the center hole is a different size. I was hoping that I wouldn't have to replace the whole pump.

Even if I/we/they don't know, if you post up specs on the hole size, you might get some imput that way too.
