How do you remove the pass side air bag?

I got lucky scouring the wrecking yard today and found a 94 camaro... I need to get the passenger side air bag out but can't see how exactly it comes out... I pulled the dash because I needed the a/c airbox... After I got that I removed the 4 nuts behind the air bag plus the 2 screws on the top... It didn't budge... What other bolts do I need to remove? There's a rivet in between the 2 bolts on the top... Does that need to be drilled out? I looked and didn't see anymore bolts to remove... I'm guessing some are hidden under part of the dash pad??? I did a search but found no help
