These swivel plates only fit VW T5 vans with single front seats. If you have a double seat swivel on the passenger side you are better off with the non-offset version or there will not be enough room for both seats to face backwards.

Kits include:

Swivel plate and bolts to fit standard VW seat boxes. 
Swivel plate mounts between your original seat bases and the original seat slider rails 
European TUV safety approval
Seat height increases by 43mm 
Automatically locks in place facing forward for driving 
Swivel is located offset from the centre so that seats with armrests can rotate a bit easier


Note: To rotate drivers seat the handbrake must be released momentarily, then re-engaged once the seat is facing the rear. For seats fitted with up/down height adjustment (that is most of them) you will find that you probably need to pump up the seat height to allow the seat to rotate without the grey plastic trim around the base catching on anything.
