Still can't find NSS

Neutral safety switch.....I went to the sight you suggested and still didn't find it on my 1998 Grand Cherokee Laredo. Went to Auto Zone and they called up the NSS and the part was way smaller than the picture on the site and it only cost $10.....are we talking the same part here....the part at the Auto Zone was held onto transmission with a lugnut and 3 prongs coming out of it. Help! I am confused. I still haven't found the NSS yet! Thanks for any help you can give! Looked all over
the transmission, been all over the site reading posts and I am stumped!
