55-56 Hudson-6-308 Exhaust manifold Wanted

Hi,

I have a 55 Hudson that I am trying to get ready to drive to the Reno HET national in July. I recently discovered that it has a nasty crack in the exhaust manifold. Does anyone out there know where I could get another manifold? Only 55 and 56 six cylinder will work. Thanks a lot for any info.
