    Exhaust manifold 64-66

    Hello, When my manifold on the driver's side is broken I need to get another one. So my question is: Is there any difference in 1964.1965 and 1966? My Buick is an Electra 225 1965, but the engine is a 425 in 1964. Is it the same manifold for double and single exhaust system? BRG Per Fruck

    340 headers
