I have a spare full width one here out of a 74 westfalia. The mechanisms are in great shape. The wood needs refinishing as does the laminate. Seat covers need to be replaced and there is no rear cushion. It would take about 4 yards of material to recover the seats and make a new rear cushion. Foam is actually not bad. Westfalia material is available online from a number of sources as you probably know. A very similar laminate to the 74 style is available locally.
I was going to redo this one but another one came along, actually a whole interior.
I am open to offers or trade/partial trade for Bus parts or a set of late Vanagon front seats.
