Hydroboost setup for body drop!

I hope someone knows the answer to this question.  I am body dropping my 2004 silverado real soon and I need to get a hydroboost setup.  I wanted to know exactly which one I need or if any will work?  And I really wanted a chrome one?  Anyone have a direction to send me?.....     Also is it worth buying the flex-a-lite electric fan kit for my truck for $500 or two fans for $100 each and mount em to the radiator?   


Thanks  

picked up a hydra-boost and found a electric fan....  Here's the next question,  Will a chrome gm master cylinder like the kind on ebay bolt up to the hydra-boost unit .  The unit is a OEM booster for a 06 1 ton chev.... 

hey whats up i have a bodydropped silverado. as for the hydro-boost i just used one off of a HD truck. and same with the master cylinder. you just have to block one line off. cause the truck will not crank with it open. the stock brake booster has one extra line than the hydro boost.

yea the line he is talking about is the vacume line  just cap it off and youll be good  its an easy install   the master cylinder i have is off of a astro van  you need  a mastercylinder fro ma vehicle tha thas a hydro boost  cuz the bores are different and the ywont bolt up right

yea lol thanks for making that clear. mine didnt bolt up as well to the fire wall either
