I havent purchased one yet, but I was looking in a Jegs catalog (dont laugh) and they list a LSD for the 240sx. It is about $330. Looks like it is only the gears and will need to be shimmed. I talked to them, they say its a direct swap.
Like I said I havent bought one, just inquired about it. For all I know it may not be a true LSD.
