WTB L/A crank pulley (measurement correction)

cast iron water pump?
Pulley I need is off of a cast iron water pump motor, but mine is not. Mine is aluminium, but I need the shorter crank pulley so belt will line up w thicker fluid damper. I have one off of a 273 that lines up perfect, but it is slightly bent, if nothing else I will attempt straightening it out. What I need is 1.5" from mounting surface to center of the belt. Any 69 and earlier small block should be the same. I got all kinds of later pullies that measure 2" 70 and later
