What factory fan shrouds will work for my 73 challenger please

[challngd73]

I've been running my challenger without a shroud since I've owned it.  It reaches a max temp of 206, and I'm guessing a shroud would lower that.  Anyone know what factory shrouds I could pirate out of a junk yard that would work? Not worried about originality.  Car was a 318 factory air car, now sporting a warmed over 440.  I believe it's the factory correct radiator for a 318 ac car.  Thanks in advance.

206 is not by any means a high temp 

 If thats as high as it gets, you dont have a problem

I believe your 318-A/c car would have come with a 26" radiator, the pre 71-B-body or 70-74 E-body should work.
New reproductions aren't bad  http://chucker54.stores.yahoo.net/rafansh.html
22" is harder to find and pricier.

Thank you for the reply guys.  I know 206 isn't terrible but a little cooler wouldnt hurt.
