As Steve said, a Nov. 29 did not have a schroud. Is the schroud you purchased have a tray at the bottom for headlight wires or no tray? The very early fan schroud, referred to as a "Tabby", has a smaller opening for the fan than the later schroud. If you have the later schroud, I suspect the recoring of your radiator may be the problem. A local radiator shop, when recoring a 28-29 radiator, would call me and borrow a radiator shell so he could check to see that every thing lined up properly.
