Looking for a 1974-76 roller

[McNessor]

I have an orphaned 1974-vintage, 400 engine, and I'd like to find a Penton roller/chassis to put it in.
1974-76 vintage preferred, and a high-breather if its a 76.
The more complete the better, but I'm open to ideas.
A Northeast or New England location would be nice too, so I could pick it up without a major roadtrip.
I'm posting this here because I really enjoy being a new-ish POG member and don't want this forum to disappear! Thanks!
