When building a Factory Five without a donor, there are a lot of things to consider, such as fasteners, brackets, and other items that are supposed to come from the donor disassembly. One item you are supposed to use is the Mustang's fan shroud. Since we didn't have one, we had the option of purchasing a replacement shroud from a Mustang vendor or Ford dealer (or finding a used one), or going another route. When we saw the So Fast fan shroud for the FFR aluminum radiator ($99 plus $10 shipping) on the ffmetal.com Web site, we thought it was the perfect answer and would look the part on a Cobra. We even had it powdercoated to match our other engine-compartment parts. The shroud is easily installed with rivets or screws. Here, the kit-supplied electric fan has been installed to the shroud, which we are riveting directly to the radiator mounting ears.
