Mine was the tan/brown. There were holes in the sheet metal behind the dash, once you drop the glove box you and just barely see them. The grab handle comes with threaded studs and nuts, so was an easy bolt-on once you gained access to the backside.
MTSN- no real airbag issues, AFAIK. In fact I had similar concerns and remember a post somewhere where someone found one with the airbag deployed, with this grab handle, and all seemed to perform as functioned. But hey, with any mod there's always that risk it won't crash test like the day it rolled off the lot, but you're well past that point now with the lift, bumper, tires, etc.. may as well sawzall the half doors.
