Description
These are an exact reproduction of the exhaust pipe to manifold flanges bolts for the 1967 ram air exhaust manifold. Manufactured by Inline Tube.These are also needed for adding 1967 ram air manifolds to the 1964-1967 cars.
These are the correct grade 8 hardened steel bolts to hold the flange and pipe to the manifold. This bolt set has the exact head markings and length of the originals made to grade 8 specifications. Grade 8 is a hardened steel bolt which means when you go to take them out 10 years from now they come out instead of breaking off. If you are doing a concourse restoration this kit is a must. The originals are always rusted and pitted from getting hot and cold hundreds of times.
1967 was the first year for the ram air or big exhaust manifolds and the only year that used the 3 bolt flanges. The 1967 ram air manifolds will bolt up to any 1964-1967 V8 Pontiac head.
