Hi Charlie. Would you say then that the 65 has a flange that the driveshaft slips into at the trans , and not a “yoke”. Like the yoke that’s at the tail end of the shaft as it meets the rear diff? I’m crossing my fingers that Fatscos terminology is wrong and the part is correct, because I murdered that seal while removing it. That seal I showed is currently in the mail to me now. Thx in advance for any feedback and advice…MikeThat 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.
