Master Cylinder number decode

[LM69Z28]

Hey Guys
Can you help me decode this MC # for correct application. It does not have the twin bleeder screws or stamped US on the pad so its not for a Z ....generic application? part # is either 5 or 6480848.
Thanks for the help

Can you post a picture? Neither of those numbers are any good. Are you sure it's not 5460346?

Will do the best I can, have not had much luck with posting photos. Doubled checked and the numbers maybe S 480848
Thanks for your help
