The old book number for this one is T1402, and it also shows up under 9998-413 in the parts listings, so if you're working from an older parts book or a different catalog numbering, those are the same physical screw.
It appears across a run of catalog entries from the mid-to-late 1960s, so it's a fastener that stuck around across a number of gearbox cover applications in that era. Check it against what's actually on your cover before ordering, since screw lengths on these covers can vary by position.
