Been a while since I had done this, but I think I used the Cadillac CTS-V pulley, it is smaller in DIA & the center hole fit on the Corvette pump.

Just a thought - the Volvo 200/700/900's run the Saginaw PS pumps also - pretty easy to find in the junkyards, perhaps there's a pulley on one of those that will provided a solution.

did you have any pressure issues with smaller pulley?

Smaller pulley speeds up the pump -- so more heat, more bypass activation, more parasitic loss. Have to be careful not to pulley it up such that at high rpm you over-speed the pump. Increase in speed is proportional to decrease in diameter. Flow increases, pressure should be determined by the bypass spring setting more or less regardless of speed.
