Fo you think those are specific to the "competition" models?
Since the letter is dated Sept 64,
it's after before Chuck C.'s Oct 16th start date Chuck Cantwell was involved, that's a good question to pose to Chuck, anyone have his contact info??
They reference the 2 notchback sedan "test/development" cars and a 2+2 for rear window study.
My conjecture is this is prior to the Oct ?? order of the 3 prototypes (SFM5001, 5002, 5003)
ordered mid Sept 1964so perhaps this was a general program recommendation it was up to Chuck / Pete Brock for implementation??
But in my mind it now presents a question, was the side scoop & rear window a combination of Philco recommendations & Pete Brock for "design" implementation??
The oil cooler, front brake air ducts and rear Plexiglas window are competition only features, the side scoop was likely initially considered for competition but they may have then determined the underbody version was easier, cheaper option, shelved until 66?
I have photos of the "mocked up" side scoop using a cobra hood scoop (black painted) somewhere, I'll have to search for them,
update-
t
he attached are the notchback "development car" that may have been the attempt to investigate how to implement the Philco recommendation?this is just interesting to me to fit the development puzzle together !
