boss kit for airbag or not?

[steo800]

want to get a new wheel for the car.

there is 2 boss kits, one for air bag and one for non airbag model.

whats the difference as my new wheel will not have an airbag, can i not get the non-airbag boss kit?

it's means for the wheel you are taking off, so you'll need an airbag one
