I'm looking for a set of headers for my '64 Cutlass with a 350 Rocket and can't seem to find any. My stock manifolds are pretty messed up. Any ideas where I can find a set? Or can a set for a 68-72 be modified to fit?

 

The frame on the 64-67 cars is slightly narrower than on the 68-72 cars. Some of the 68-72 headers fit, some don't. Kooks (sold by Dick Miller) fit, but they are priced accordingly.
