where can i buy a 904 tail Shaft Seal for my 273

That screen shot from Fatsco in not correct. 1965 TF904 (at least in "A" bodies) did not have a slip in yoke, it still used the flange. Just a FYI: 64 and 65 used different extension housing rear seals. However the oem part number (2464 482) referenced is correct for 1965. The seal part number for 1960-1964 is 1942 401

EDIT: Post #12 I listed the wrong part number for the 1965 seal. The correct numbers are in this post.
