So the older invoices that list 348 as H.O. and have a 611 option are NOT Ram Air because the invoice does not say Firebird 400 RA on the 348 line? Your logic fails.
It's always been a ram air III. If you would just read, QUOTE 348 is R/A III which also is HO. In 69 they are one in the same 348 = HO = R/A III. I have published material showning this from the 80's and here is proof found in the 21st century thanks to the internet bringing more paperwork(actual invoices) to light.
