The hinges from my westfalia rock 'n' roll bed have seen better days with the springy/clippy bits that lock in to place to hold the back firmly upright bent/broken beyond repair. Does anyone have a pair of these hinges going spare? They are the campmobile/berlin style ones from around '76. If so, please could you let me know a price and if possible post a picture of them so I can confirm they are the right ones. Thanks. Nick.
