need exhaust head pipe/ or just the flange. Any ideas?

Looking for the flange, or a head pipe with a flange for my slant six out of a 1964 dart convert. Looked everywhere, can not find a reasonable one, I only saw a long pipe with the flange for like $150.00 way out of my budget. O'riely sells the correct gasket, just like everyone else, but no one carries the flange, or head pipe. Any info would be greatly appreciated, I'll have my ole lady come over and clean your shop! Thanks
