Please excuse me if I "horn in" on this thread but it relates to the T10M subject. I happen to have a spare T10M, AL case and tail. The case has a casting date of 7-27-65 and an assembly date of K45 2 (Oct, 4, 1965, 2nd shift) and a tail casting date of 8-27-65. Can anyone give me a range of 6S VIN's for which this tranny would be correct or suggest when it might've been installed?
