The T-Bird electric fan came in today. I laid it on the radiator the conventional way (top side up), and saw how much it covered the side tanks, along with one of the hose tubes. For kicks, I rotated the fan assembly 90º, and BAM!!, it instantly became an absolutely perfect fit between the side tanks. I'm going to mount it like that, but first, I need to shorten the now bottom portion of the shroud as much as possible, and then close it off and seal it. Better to have the hacked side on the bottom where it won't be noticeable. Of course, the four useless mounting ears will need to go, too.
