These pins are welded on the seat frames on Type 1, Karmann Ghia, Type 2 and Type 3 and they are very useful  to fix the seat cover. The upholstery is pulled under tension over these pins and on their turn they are folded over the seat cover for an optimal clenching of the upholstery. As these clips are in fact designed for single assembly, it happens that they break off when removing the worn out upholstery. The only possible solution is to replace these pins for a nice new straight up seat cover. From now on we can deliver them per 10 pieces from stock.
