I am stupid.
I bought a car and haven't had much of a chance to fiddle with it due to the cold winter and the fact that my garage is not heated. This is also my first LT1 car. I took a quick look at the motor (in semidarkness) and concluded that the A/C compressor was there so I got on the Internet at GM Parts Direct and ordered the A/C delete pulley. As it turned out yesterday, I caught a glimpse of the air pump and on the other side of the motor, the pulley had already been installed... I am stupid.
My loss is your gain. It cost $42.04 delivered to my house. I will let it go for $35 shipped.
