Airbag gone

OK I bought a 95 GT that was a rebuild, and the airbags were removed, I have no interest in putting them back but I am getting annoyed by the beeping that happend every now and then. My question is how can I trick the compuyter in thinking the airbags are there? There is no airbag light either... I am sure the previous owner killed it or something.

Thanks for any help.

Mark.
