I have a 2004 Subaru Forester with dual airbags. I have a 10 year old, who is rather big, but needs to sit up front. Many cars have on off switches for the passenger airbag, but the 04' Forester does not. Are there any options to get one installed that anyone knows about. It is legal to have one installed if there is aneed, and I have one. Any help would be greatly appreciated. Thanks CJ
