Jim,
I'm not seeking to be spoon fed, and I appreciate the help, however I am having trouble finding the true definition of FA wings.
I have posted quotes from GCR appendix on FA aero (post #10)
I also had already reviewed the solo rules section related to open wheel cars in BM, the same as Lynn posted.
I have found side plate templates for a Swift (FA?) end plate here, provided as a scan of some painters tape:

I have read section 18 & the appendix related to BM. I see in section 18 that there is a square footage of wing specified, but that is for "Specials" or AM cars by my understanding.
In the appendix, I see references to FA spec, with allowances for additional gurney lips.
I am sure I am missing something, so the help that you & others offer is valued.
