Fan shroud for aftermarket aluminum radiator

Hello all. Once again, another brain-buster.

I bought a 340/4speed combo from a member here and the 340 had a flex-a-lite fan mounted on it. The setup also came with an aluminum radiator (seen here http://www.ebay.com/itm/30069248569...m=&sspagename=ADME:X:eRTM:MOTORS:1123&vxp=mtr ). I'm about 95% sure this is the same unit as the dimensions are the same (22" wide, 20" tall, 3" thick). Also, the welds, mounting points, and inlet/outlet are all the exact same.

I'm wondering if anybody has ever seen a way to mount a stock-style fan shroud to an aftermarket radiator. I know they sell the custom aluminum ones, but I'm trying to avoid fabbing with aluminum as I do not have the right welding equipment. I'd also like it to function better than the aftermarket units (i.e. allow the fan to properly pull the air through the shroud and not just mix it in the engine bay). I'm willing to fab up some brackets, but I'd like to be able to use a stock style fan shroud. Do any of the stock shrouds even have similar dimensions? I don't have a lot to go on here as the car is stipped down and neither the car nor the motor came with a stock shroud.

Any assistance would be much appreciated. Thanks all.
