The difference between a TA vert turning up and a Bird with a Chevy engine is this: A TA vert is going to get recoginized because it can't hide. The trim tag would be different from any other 1st gen. A Bird with a Chevy engine isn't very noticeable. You say that you haven't seen one in your quarter century of scrounging. How would you know it if you saw it? You would have had to see it and order a PHS.
