My 65 convertible has developed an exhaust leak. I thought I would be able to get by cheaply and replace the gasket between the manifold and the exhaust pipe. No such luck, it helped but I find that I am in need of a left side exhaust manifold for the 413. It appears to have a few small holes in the top side close to the bolt area, but the leak is in the cast iron not around the flanges. If any one has a set of exhaust manifolds they would be willing to part with reasonably please let me know. The reason for the set is that the heat riser is also leaking on the right one. I might as well change both and get it over with. Thanks, Joe 64 coupe& 65 vert
