fan shroud help... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am in the process of a 5.3 swap on my '71 GMC and am coming down to what fan shroud to use. I have looked through the archives and cam up with some dimensions, but none of them seem to be close to what I have. I have a measurement from the front of the radiator core to the backside of the fan blade of 7". It seems as if the only one that will come close is the 4wd shroud, but I would have to shorten. What is everyone else using on their swaps. Is there a chance someone could take some measurements of their 4wd shrouds from the front of the core to the end of shroud. I have a big block shroud here but it is WAY to short!!!
Any help is appreciated!!
