1963 B Body Borg Warner T10 transmission?

[fast67vellen2o]

I just picked up a 1963 Borg Warner T10 4 speed that came out of a B body. Was this a one year only unit? I thought you could only get a 3 speed in 1962 and then in 1964 the 833 came out. What was this unit originally installed behind? Thanks in advance.

T-10s were used in early GM cars and also in Fords as well as the 63 Mopars.
