Easy Question, but I don't know

I really should know this, I have a 1994 Nissan P/U 4X4 with 3.0 motor, what should the spark plug gap be? The guy at Auto Zone said .032 when I took the plugs out they were a lot bigger then .032, I called them back and they said .032 What should the gap be?
Thanks
Joe

some plugs can have different gaps but if autozone told u .32 then use .32...
