Can anyone tell me what the part numbers for the original 1968 to 1972 big block exhaust manifolds were? Bought a set of 3994045N and 3994046N but the only info I can find says they are for 1973 to 1975 police 454. Tring to get parts to put an exhaust system together but I am afraid the parts won't match these manifolds.
