I have not seen a 1965 Fastback that did not have angles brackets. Does not mean some very late ones got them. I have a fairly late San Jose car built mid July that still has Chrome Angled Brackets. Since it was not only the Bracket but the Folddown floor it bolted to was different so I want to say they probably would have been change made in 1966 when changing everything else over. They are listed as fitting late 65 but use a 1966 part number.
