You could always go with a z32 NA or J30 diff cover which holds more fluid and has cooling fins if you're skeptical but unless you are doing continuous laps at the track I do not see the diff generating enough heat.
My guess is the fluid got really low at some point (happened to me once...noticed it was low so filled it to bottom of fill hole and the thing whined and blew up anyway) or improper installation.
