Where are the custom 200Silverado parts???

Merry Christmas Everyone!
I am working on my Stock 03 single cab Silverado 4.8 and want to purchase Chrome/polished aluminum parts to clean the engine up. I have found some parts but does anyone know where I can get a polished Alt/power steering bracket like the stock one. I haven't seen one or if a company makes a billet one that will work.
Also I want to get rid of my stock clutch fan and replace it with electric ones to open up the engine compartment. Does anyone know of a how to for this or if someone has tackled this. I believe I will have to change the shroud.
