Pulley help please.

[ChevyDude]

Pic Is an example and not the truck I am asking about. Pictured is my K-10 383 set up.

Hey board member Cethern was over yesterday and pointed out that I had a LWP on my 2wd engine (that is sitting on a stand) but yet I had the alternator mounted on the drivers side. Well, the truck came with the ALT on the Passenger side and I bought the brackets to put it back on the drivers side where I think it belongs. So I know I need to get a short water pump, the question is the pulleys. This truck has PS and will have air, so can someone set me in the right direction as to what pulleys I need to buy. I am going to purchase those nice polished aluminum ones .

Here is a pic of my K-10 that has a 383 in it with AC and PS. As you can see in the pic the Water pump pulley is a 3 row and only uses two and the crank pulley is a 4 row and uses 3 but does use the very outside for the PS. Any help is appreciated.
