"...One car on this list I cant quite figure is the Heath SS/F=9.50 67 Firebird..."

Good catch ! I didn't even look that far down the list. Not familiar with that name.

I can't figure all the early classing. But, the pics I have of two '67 SS Birds show them in F. And they are both hardtops, or coupes, or whatever the non-convertible Birds are called.
