That is a great deal.
Just a heads up -
1996 and prior seat bolt patterns are different than 1997 and later.
1996 and prior seat belt receiver is bolted the the floor. 1997 and up are integrated into the seat itself.
Some vans have a PC control box mounted under the driver seat. This swivel will not accommodate that box. Check first! (And - the driver and passenger swivels are different, the floor mounting holes are in different locations)
Pretty sure the swivel in the picture appears to be upside down. That is the floor plate appearing on “top”. The seat tracks mount to the face that is resting on the ground.
