What is this pulley and bracket for?

It is in fact, the water pump idler on a 70 up smallblock with AC and no power steering. They are very rare!


You are correct. There is a Duster here that has that Idler. This car had manual steering but power steering was added. It was left on the motor so it don't get lost. I offered buy yours for a spare. $100 is way to much for me. Give me a realistic price or trade for whatever? Steve
