New Dash Airbag help please

Just got this dash installed i cannot get the passenger airbag to go in the tabs hit that mounting bar in back and i cant to push in any farther. I neede bout an inch to make it flush and bolt it down does anyone know know if this mounting bar looks funny i dont have old dash got rid of it after i got everything transfered. 1994 mustang do they all have the same airbags up till when?? Thanks for the help guys.

Well i was doing some checking on ebay motors last nite and someone had one that looked like the one that i have and they were trying to sell it as a cobra dash the bars are pre-bent like mine,yours look like they are straight i dont understand why my airbag won't fit and i don't want to not install them granted the Nevada does not have a state inspection just emissions in some counties i don't want to take a chance in case later on i move to another state.
