Dave that not quite right. 415 and 501 shared some diff parts. Like diff pulley, rings etc, but you couldn't put a 415 rear diff in a 501 or the opposite. It was from the ta05 that the 501 took it's drivetrain.
Either way in order to have a gear diff they'd need a completely different pulley on the 502 so unless they do that you won't be able to run it. As for gear diff in the 511 maybe the ta05 geared duffs might fit...
