I know this sounds silly, but while working on my shift linkage this weekend, I noticed that the Toploader in the car is missing the drain plug. There is a machined flat on the bottom of the housing, but its solid. No hole for a drain plug. Tranny is a RUG-AW in '70 Boss 302, although this identification is based on the tag hanging on the side of the housing. Factory mistake, or am I looking at a non-original housing?

I remember reading somewhere that the later model toplaoders did not have drain plugs. I have a 71 Sportsroof that the PO removed the 4-speed for an auto. I am going back with the 4-speed and the case I found is for a 71 and it did not have a drain plug. I have since torn it down and had my machine drill and tap one for me. Hope it helps.

Starting sometime in 68 the drain plug was eliminated. Yours is correct for your Boss 302. I have the same one in my 70 Mach1.

In 1968 Ford changed the case internally to add a big magnet and in mid year 1969 Ford stopped putting drain plugs in the cases but left the outside boss. Yours is correct.
What Art said about the bottom tail-housing bolt is a pretty neat trick to drain the grease.
