This is a continuation if a thread under "hot rods." Maybe we need tech help.
Some of us with various models and ages of MBs get flapping hoods at higher speeds. My 86 560SL hood starts to boogy at regular highway speed. At first I thought my hood was unlatched and held only by the safety catch, but it latches securely. Is there an adjustment? Could it involve the little rubber wedges about a third of the way along the hood opening?
