'65 Formula S with "factory" 727 and 8 3/4?

727 never happened in an early -a on assembly line. Conflicting reports on 8 3/4 ‘s being installed on very late 1965 production models especially 4 speed cars.
What is clear is these cars were readily being sent back to dealer for a damaged 7 1/4 under warranty. Sure many were actually replaced with an 8 3/4 by dealer. As far as 727 highly unlikely even dealer would replace a 904 with one but this was mid 1960’s and anything was possible at dealership.
