"Since my flat fender already has the saginaw steering conversion to allow for the installation of the Buick V6 replacing the stock manifolds was requred. (Unless you can find another right side manifold to place on the left side- old Buick manifolds are rare) These headers were half the price of custom made ones and they do fit. They feel sturdy and have a good warranty. I was pleasantly surpised with the flange to 2" pipe converters included. This helped me connect the quieter mufflers easily. Origonally I was worried because the headers I ordered were for a 69 CJ5. A friend said they might need slight alterations to fit the CJ2A. A nice fit with room to spare. No alterations required."
Pros: With minimal cutting of the fenderwells they fit perfectly
Cons: Painting the uncoated headers is a pain and wrapping voids the warranty
