7.3 powerstroke intercooler
 

I'm looking at buying a 7.3 intercooler, it is new. Not sure how to install/rig up some sort of contraption.

anyone who has done this...successfully, your input would be appreciated.

Its alot easier to do with an intercooled grill, more room. Otherwise you need to cut up your stock grill pretty bad.
