Lots of negatives involved.
I'm not aware of anything to put
back in place of the airbag.
If you just take it out, the electrical
system is going to show a fault and
light up the instrument panel warning
lamp until it's properly fixed. I don't
know about other states, but here
you won't be able to get a state inspection
with the truck in that condition. No
inspection here means no registration.
If you have a traffic accident, and the
insurance company finds that any safety
system has been disabled, they'll deny
any claim you have.
Not worth the trouble.
