After reading Tony's reply, I now realize what your question must be
about: the ventilation holes on the right-hand side. On mine, there
are two, both 6.5 inches high, the front one 4.5 inches wide and
positioned roughly over the third through thirteenth cards, the rear
one 6 inches wide and positioned roughly over the 8th through the
last slot of the second backplane unit. Both holes have a grill
of hexagonal mesh, about 1/4" spacing, welded on the right hand side.
Does this help?

And, to be more explicit about the lips, the front and left lips
are about 3/4" of an inch. And the back panel has two slots, each
roughly 2 3/8" wide. I think my maintenance books might have a drawing;
if I find one, would a fax of that page help?
