Has anyone installed the passenger side airbag in a 1999 Chevy Suburban 1500 4x4 (5.7) ? I've replaced the drivers side which was quite easy and explained in the Chilton's manual. There's no explanation in the manual on how to replace the passenger side. I know there are four bolts that hold the air bag in, I can easily get to two of them that are directly behind the front face of the air bag. I can not get to the top two that are facing towards the fire wall. Anyone have suggestions (other than taking it to a dealer that wants to charge close to $2,500 for replacing it?) Greatly appreciate.
