Finally the last piece! After two years of searching, placing craigslist wanted ads from coast to coast, gougers, scammers and hoarders, I found a 3462017 for a bargin price! Somebody on craigslist saw my ad and told a guy who racing his car in 71, took off manifolds for headers, been sitting ever since. I knew they were still out there in the corner of someone's garage. And just 20 miles up the road.
