TR3A battery box drain hole question

[kengano@advant.com (Gano, Ken)]

        In my rust busting zeal, the bottom of the battery box went many months
ago (for that matter, I'm not sure it was ever there).  Anyway, now, upon
rebuilding the battery box, I find I have no reference for the size of the
drain hole in the front.  Does anyone out there know what it's suppose to
be?  Position I can figure from the position of the other hole in the
tranny cover, but I'm pretty sure that the size was much bigger.

        Thanks a million.
