Folding seat hinges for the VW T3 T25 Vanagon

Long trips with the T3 and perhaps no high roof or pop-up roof? Or maybe simply traveling with more than two people? Then a folding bench is a must. For driving, eating, and living, you can sit comfortably on a bench with a backrest. For sleeping, the bench folds down, transforming the interior of your T3 into a full-size bed approximately 190 cm long.
The fittings are not screwed to a plywood board as originally intended, but instead have their own base/foot/support made of sheet steel. This ensures a precise fit. The seat angle can be adjusted using side adjustment screws.
For those who like to carry a little more gear, the hinges are also available in a raised version of +9/+12 cm. The support plate is the same, and the fittings can be mounted at either a 9 or 12 cm elevation.
