The cable that unlocks the Karmann Ghia front hood runs from model year 1968 in a PVC hosing through the front hood. This hosing prevents that the cable gets clamped or damaged, though when they are old the outer cable can harden. Consequently this protection can  break and tear when manipulating. The adjustment of the front hood cable is no longer properly working and you can't unlock the front hood anymore. We recommend to replace the damaged outer cable at the first signs of age by a new correctly fitting item. Available each from stock.
