Hello! with my 95 caravan the driver’s seat is so depleted that I really get back problems. (either because of the seat or because I reached the 30 ) The 2 wheels on the side no longer work. Did anyone find the same problem and a cheap solution? PS: now I looked at Ebay and saw beautiful seats with door panel made of partial leather of 3 liters. Can you build everything or do you have to pay attention to anything? Bj.? Limo or Caravan ? etc.?
