That is the measurement for a 727 in a Dart isn't it?
maybe not;
my little Govier book says has no listing for a 904/8.75.
The closest thing would be a M/T and 8.75.
They have one application for 70/71 and it is 48.96
They list 7260 joints on that
But that shaft would have the large slip-yoke on it
It is pn2883760
