Forget about finding "how many were built like this". It's not gonna happen 35 years after the fact...
The only breakdowns I have state that there were 46,886 two-door hardtops built, and the breakdown of how many at each assembly plant.
While we're grateful that PHS exists, much of the info has not been sorted through, as nobody is willing to fund such a project. In addition, some of the records are unreadable. I found this info in the "Judge" section of the PY forums.
Just enjoy it!
