1970 e body disc brake booster ID

I was wondering if anyone could shed some light on identifying my boaster for my car. It's a 440 six pack with power disc. From what I've read the two part numbers that should be 2944490 and 3420987?

The only thing that comes close to this on my booster is 294498L9?

Please let me know is what I have is correct? It appeared as if had never been changed, but given how old the car is anything is possible.

And one more..

Close up of what appears to be the part number..

I have a 70 Cuda V code and here are some pics of the numbers of my booster.

Hmmm, looks like the exact same booster.. Thank you for the pics. I assumed that this is the correct booster for my car. Maybe someone will chime in and explain yet another mopar mystery!

Hello
I am digging out this old topic trying to understand the way booster are coded.
2944298 E 1 is from my 71 Challenger six pack, produced in march 71
3461025 F 0 is from my 70 Challenger six pack , produced in January 70.

Can someone shed some light on date codes? Are these parts the correct ones for the cars? Thank you

I also found numbers on my 1970 Bendix boosters and would like to know more about this.

This first one is from my AAR Cuda,
The second one is from a 70 Cuda that I parted out, looks to be double stamped, and
I have a third one from a 70 cuda that I parted out with no stamp.
