That's it!.
Thanks Rick, I'd forgotten it was John Z just remembered it was someone reputable..
Among other reported factory '67 B-Body L72 cars I've heard of are a few Canadian cars including Canadian Pontiacs..
As many here are aware, Canadian B-Body Pontiacs had Chevrolet chassis and drivetrains..
The twist to keep in mind w/ this is many (but not all) Canadian built Chevrolet powered Ponchos and Chevys had unique suffix codes that had alpha/numerical digits and included in these were the Tonawanda built MK1V's..
What I'm getting at is an unknown '67 B-Body L72 suffix for Canadian production is a very real possibility too!.
