Wait, Don't toss this idea out just yet,
how willing are you to change parts?
you may be able to move that part from one seat to the other.
then you could work around the airbag issue, the seatbelt issue, etc......
I am going to say this again, some people mess with stuff and some don't. I think the ones that don't should let the ones that do keep messing with stuff, we might come up with something better.
the alternative is keep slamming those that try something new until they stop posting and you never get the good ideas that others discover.
your choice.
