Part color code seat back

[mark2003]

I am looking for a front seat back and do not understand the last 3 of the part number I think it is a color code
does anyone have a list? BAB vs BAC vs CAA.............

The front seat back is connected to the seat itself with 2 screws that are mounted under the seat.
Everyone misses this, and they crack the back off the seat. Both sides of by black are broken and one side of my silver. (driver's seat)
I doubt you will find one except on a seat.
