I have for sale a vw t5.1 GP front passenger captain seat with a genuine factory fitted swivel base. These are extremely rare and the seat is as new. Choice of the new Robust leatherette fabric or place cloth.
The seat is not cheap but was very expensive to buy in. Swivel base does not rock and is very solid. There is no height adjustment on factory swivel seats but it is not needed on a passenger seat.
Give me a ring if I can help.
Kombi seats, Caravelle seats, front captains seats always in stock.
