I don't believe so. The dipstick was deleted several years before the 4
synchro box was created (at the same time the main casting was changed to
accommodate the later starter, at TS50000); and if I recall correctly, later
3As didn't even have the hole in the tunnel to access the dipstick. But as
I mentioned, it's easy to adapt the dipstick top cover to the later box;
possibly someone knew that even 30 years ago ?

The 4-synchro box has a large cylindrical bulge on the LH side, right behind
the fill plug.

You'll need the OD mainshaft to match the gearset in the box (meaning a
different shaft between 3-synchro and 4-synchro). The adapter plate also
changed slightly, but I believe the early plate can be modified to fit the
later box by removing some metal with a die grinder (to clear the end of the
countershaft). But since the early plates were somewhat weak anyway and
prone to leak; it might be better to just buy one of John Esposito's uprated
plates.
