I have a 1978 Ford Econoline 350 van that has front bucket seats (I should also note that it's a motor home). I'd like to add another seat in the front because I need a seatbelt for the car seat. There are no other seatbelts in the vehicle. Is there any way to convert from bucket to bench seats (don't forget about the dog house between the two seats), or to add a small center seat or something?

thank you.

 

when my parents were first married, they had a van that they traveled around in (no they were not hippies) and for my older sister's carseat, my dad just bolted it to the floor right behind the dog house, and that seemed to work fine.
