Thanks for the reply!
P. 3, part D15 (two of them). They're just little rectangular boxes, 5 sides closed, one long side open, about ΒΌ" long. They mount in two slots just forward of the aftermost starboard hangar deck door on either side of a hull opening. Going thru the instructions, nothing seems to mount on them.
Any help appreiated. BTW, does Clancy's Carrier book cover Nimitz?
