Rear Axle ID

[Kansan]

Can anyone help me ID the original rear end from my 73 Cuda based on the below information?

Thanks in advance.

8 3/4" Suregrip (489 case - 1 7/8" pinion) with 355 gears. Propeller shaft (drive line) confirms 8 3/4" rear also.

Awesome....Thank you...I can find all kinds of ways to decode 1970 broacast sheets but not so much for 1973.
