Be careful around the airbag sensors, even if the battery is
disconected they can go off, seems they have a backup
just in case the battery gets knocked out of the vehicle
in an accident.
To be totally safe I think if you remove the sensor you
will be fine, most of these sensors are a velocity (spelling?)
type and react to sudden stops, I.E. impact, so you should be
able to make your bumpers and have airbags too.
Is that like having your cake and eating it too
