What do these #'s mean?

[Martin64]

I just acquired 3 transmissions, 1- 2 speed "Power Glide"
and 2 350TH.

On the 350's, the housings are different.

One comes to a "V" at the top and the other comes to a "U".

On the "U" shape top there's a casting number 864Q239 and below that is CFD9 and then in a circle that's divided like a Mercedes-Benz hood ornament are the numbers 10-75 at the bottom (inside the circle) and 27 in the top right (also inside the circle).

The other 350 with the "V" shape has the numbers inside 2 circles that look something like this:

626 1 70
1675 T 54


The 626 and 1675 are in one circle and the 70 and 54 in the other circle.


Do any of you transmission guru's tell me what I have?
