Thanks - that was most of what I was needing.  Unfortunately it doesn't
identify the real estate occupied by C1767 there, nor in the component
placement diagrams.

Can someone point me at the right spot on the board?  If it's got enough
room for the same 3528 cap we're looking at for the big-C rework (which I
doubt, though it looks like it will fit for the big-C position) that would
be great.
