Cracked exhaust manifold

[pint4]

The center section on my 1933 Series 60 Buick exhaust manifold has a fairly significant crack and needs to be replaced or repaired. I am told the car will accept Series 60 Buick manifolds from 1933, 34 and 35. I am looking for a good replacement. The option is to get it repaired. Are there shops out there that repair cracked exhaust manifolds? I would prefer to buy a replacement if anyone has one for sale. My email address is: pint4@new.rr.com

Thanks.
