need an extra back seat

Does anyone know where i could find a place that sells and possibly installs a third row seat. i really need more seating.
Thanks for any help:flash:

depends what car you want it for
you cant installa fird seet for some cars

If you don't have an Ext then there is no where to put it. The second row seats will not allow you to access the rear area anyway. Most likely there would be a safety issue as a regular TB has no provision for seat belts. My $.02.
