need a fan shroud for a new rad...

I ordered this online last night... http://www.shepherdautoparts.com/all_aluminum_radiator/plymouth/duster/1973/5dot4l_v8_340.html
and I'm gonna need a shroud. I'm putting this in my 72 duster that I'm guessing had a 22 in it due to the measurement of the space where a rad is supposed to be. No rad came with the car when I bought it. Recon I'll give it a little "nip and tuck" so the 26 will fit. I want to go electric if I can. That Mercedes fan is waaay out of my price range (they proud of that SOB!), I like the HHR but don't know if it will cover the core. Will go clutch if I absolutely have to but I wanna try electric first...
