Sale is pending on Swivel base. I'm not sure what year it's out of. The quality seems legit though. I'm not sure what side it's for honestly. The lever is on the passenger side of the seat base which would lead me to believe it's a driver's side seat base. However, I had one installed on my passenger seat in my van and the lever was also on the passenger side of the seat. I suppose you would use it for either side.
