CORVETTE HEADERS 68,69.70.71,72,73,74,75,76,77,78,79,8

I HAVE SEEN A LOT OF STAINLESS STEAL HEADERS FOR CORVETTES APPEARING ON okay. I HAVE A C3 1979 VETTE AND PURCHASED ONE PAIR AND MOUNTED ONE SIDE. IT WAS 2.5 INCHES OFF THE STREET.. ONE SPEED BUMP WOULD CRUSH THEM. THE PROPER HEIGHT FOR A C3 HEADER IS 18" THATS TOP OF BRACKET ON MOTOR TO THE LOWEST POINT OF COLLECTOR COLLAR... ASK FOR A MEASUREMENT BEFORE ORDERING..
