Those fittings in the corner are for the fill hose and fill vent, I
reckon.  On the inside the studs are sender terminals for the water-level
LEDs -- the hole at the bottom appears to be the outlet fitting for an
external hose and pump.  My '84 has the internal pump but I don't know when
they began doing that.

I haven't heard any good news about replacement caps, and I don't know if
all the caps are the same.  Mine is a two-part polyethylene affair which
tries to let the gasket tighten onto its mating surface without a lot of
scrubbing along it.  If I had to I could make some brass caps that would
work (one-piece), but they wouldn't be cheap.  Might be able to use an
O-ring seal.  Mine appears to have 3 mm thread pitch with about 35 mm major
diameter.  Made by Hella, getting some surface cracking and one possible
real radial crack forming.  The tube from the tank has 33 mm OD if I
measured it right standing on my head in the dark.
