I just ordered Item #:91042010 from these guy's>> FAN SHROUDS
I will be using it with this HD Spal 12" fan I just received yesterday via FEDEX >> My NEW FAN link
I searched for pre made fan shrouds, and found quite a few variations, but I have a very tight area to put a fan, and it has to be toward the top of the radiator, so I think these shrouds I linked above gives me something to work with.
The only part I may modify, is to cover all the cute air holes with rubber flaps, that will help the fan pull more air thru the radiator while sitting still...
