Well, there is SORT of a radiator drain plug: the fan switch, which is a big brass plug at the lower right-hand corner of the radiator.
Takes a 29mm socket, I seem to recall... which means that from a practical perspective, taking off the lower hose may be the easiest route if your biggest socket is a 19mm. :-)
My favorite coolant-draining bit on any car: my 1967 Giulia Sprint GT 1300 Junior, which had a little bronze faucet ON THE SIDE OF THE BLOCK. Made it soooo easy to drain the engine as well as the radiator.
