Do a search, its around here somewhere. The last sentence of your post was a little vague though... did you mean either a AIR delete pulley, or the part # of a new belt? If you're open to the idea of using a shorter belt, its really easy, I believe I wound up using a 98.6" belt. I believe there is an AIR delete pulley, I think someone mentioned it while I was posting questions when I took my system off.
Dont know if this can be used on the F cars but theres a kit for the L98 Vettes.I have one on my car and really like it.It uses my stock belt.
Heres a link for the pulley eliminator.

You may want to call them see if they make one for the F car as well.Im pretty sure the F cars have a different accessory set up for the serpentine system then the vettes.
If it helps,my kit came with rubber block offs for the a.i.r check valves,but instead of using that,I took off the stock check valves and got some round steel pipe plugs from the hardware store 1/2 inch thread size
(F car may be different thread)
and screwed them on tight..used a little high temp anti seize and tightend them on with vise grips.
Looks great and dont leak.Cleaned up my engine bay alot.Easier to access the front spark plugs now.
Good Luck!

Yeah... all you need is a little longer belt and to remove the pump. Look in the tech part of this site its all there on how to do it.
I did the same as bill... I bought the 1/2 caps from the hardware store. I installed 1.6 rockers at the same time, so IM not sure if the power increase came from the rockers or both.

On the 88+ serp f-body's you just need a 4 inch shorter belt and it works fine. At least, on all the firebirds I've worked on..
On the older camaros, and such ive worked on you just remove the V belt going to it.
Tho, even tho I've worked on many f-body's, they were all similar (88-90 trans ams, formulas, and some 2.8s). And only a few camaros. So I imagine there was a few different belt designs.

Why use the delete pulley? All you need is a longer belt and to remove the air pump. One less pulley too turn...You just have to route it around the pulleys a little different. Thats what I did on my 90.
