904 torqueflite

I bought a 1964 Plymouth /6 with transmission from a Belvedere, the numbers on the transmission near the oil pan drivers side are 2466093U 1081152. Could anyone fill me in on what they mean? I tried looking them up but no luck. I'm trying to find cables and maybe a bolt on floor shift or a column shift to put in my 46 dodge truck. Definitely a new guy with this stuff and appreciate all the help I've gotten so far, Thanks Brando
