Transit Van Seat Swivels Available at Van Upgrades
Here are a few photos of the Transit seat swivel base made by Sportscraft.
These are a nice heavy duty base that will allow you to swivel your seat around for additional rear seating. Sportscraft is widely used in Europe for RV conversions. These have also been a popular item for the MB vans in the US for well over 10 years.
