Planning to purchase '03, '04, or '05 Tahoe.

Having trouble finding the 'right' one with side air bags.

Is it possible for a dealer to install these things?
Approximate cost for driver side & front passenger side?

I've heard that the seat, etc must be replaced and some
electronics installed.

Thanks,
B

these side air bags do entail more than just the bag, as they are often mounted in the seats.
