1/48 UH-1F conversion

I recently purchased a decal sheet from Wolfpack Decals "Choppers Galore" that has, in the extensive historical and modelling specifics for each of the subject aircraft, reference to a Finescale article that deals with converting the 1/48 Monogram UH-1B/C to a UH-1F/P.  When I tried to access this, a note popped up stating that this was too old and not available anymore.  Does anyone remember this or has anyone tried this conversion before?  I do have the Monogram version of the Air Force Huey  (unfortunately, without the box--and even though it is terribly incorrect, it does have the roof mounted rescue hoist!).  I'm sure the conversion process is extensive, but I am still interested.  Funny that Italeri did not make this version in 1/48 several years back when they released many of their helo models.  By the way, the decals from Wolfpack are just great!  The information, color schemes and building notes included make them a real bargain, not to mention that Air Force helos are not a very extensive subject.  They even have 2 marking options for the CV-22B Osprey and the MH-53 Pave Low, for those of you, such as myself, that have invested in the Cobra Company Pave Low conversion, detail, and weapon sets (I PLAN on building at least two fully tricked-out).Any info or leads on the Huey conversion would be appreciated.
